Twenty years ago this week, at the age of six months, Dolly the cloned sheep was unveiled to the world amid much controversy. Newspapers proclaimed the scientific community was "in an uproar" ; others said the creation was "anticipated and dreaded" and the announcement prompted inevitable claims of human cloning being close to reality.

However, more than two decades since the sheep's "birth", full human clones are non-existent and cloning technology has remained, mostly, contained to scientific laboratories. At its simplest, cloning works by taking a genetic part of an organism and recreating it in another place. Dolly was cloned using a process known as somatic cell nuclear transfer SCNT which takes a somatic cell, such as a skin cell, and transfers its DNA to an egg cell with its nucleus removed.

In the process, the DNA can be transferred by injection or through a process using electric currents.

Human cloning developments raise hopes for new treatments

Although revolutionary at the time, this method has since been largely superseded by the introduction of Induced pluripotent stem cells iPSC , announced more than a decade ago. For example, iPSCs can be used to treat diabetes, or iPSC blood cells can be used to create new blood free of cancer cells for a leukemia patient.

In , Shinya Yamanaka, who is now a Nobel Prize winner , showed how mature cells in mice could be reprogrammed to become immature stem cells. A year later, research led by Drs. While most cloning techniques are still within laboratories, there is a commercial industry that exists to produce clones of animals. Utah State University, for instance, is cloning cows. It's also possible to clone your pet, for a fee. The cloned puppies were shipped to the UK. The firm says it can clone studs to produce quality racing horses which allow "breeders to better leverage their most exceptional animals".

It says all the pets it produces are "normal healthy puppies and kittens". There are unanswered questions about the long-term health of clones. Can you imagine having a clone of yourself, your parents, or even your siblings. Have you ever wished for someone to take your place for a minute, an hour, or a day. This may come true one day. A clone is a cell similar and identical to the cell the clone was taken from. There are three types of cloning.

Three types of cloning include gene cloning, twinning, and nuclear transfer of genetic material Clone and Cloning 1 of 4. Cloning should not continue because it can be dangerous for a number of reasons and is not morally or socially appropriate, except in cases where it could save the life of a human being. Cloning can have all kinds of dangers The field of genetic reproduction is creating a variety of unknown social and ethical consequences that are particular to our present time.

Such consequences, although unknown now, of the manipulation of nature at such a primary biological level will have disastrous effects on the generations of the future. Cloning as a new science, concerns itself with the replication of organisms through asexual scientific method creating exact replications of the parent cell Strong Essays words 5. Where Genetic Engineering and Cloning is headed this is possible. Not only is this effecting your child its affecting the whole world as well.

Many people think they only do this in humans it happens in plants and animals too.

Genetic Engineering and Cloning changes the natural possess in humans, plants, and animals Good Essays words 1. DNA cloning provides the ability to isolate and replicate genes of interest and study their direct impact on organisms. Genetic engineering and transformation provide an insight on an issue of great caliber, the increase of antibiotic resistant bacteria. The extraction and inserting of genetic material are known as miniprep and transformation, respectively.

A vector is essential in order to transform genetic material between bacteria Better Essays words 4. Also cloning will make us realize how much scientists can actually accomplish knowing how to clone. Scientists were able to clone an animal in It gave the scientists hope that one day they will maybe be able to clone a human because they were able to clone a mammal. Eugenics is also vital to American society. Powerful Essays words 4.

In doing so, it has missed the much more immediate impact of this work on how we use animals. It's not certain this would really lead to flocks of cloned lambs in the fields of rural America, or clinically reproducible cuts of meat on the supermarket shelves The discovery instantly caught the world's attention because Dolly had only one parent; Dolly had been formed by transferring the genetic material of an adult female into one of its own embryos. This process, known as "somatic cell nuclear transfer", refers to removal of genetic material from an adult cell and then implantation of that material into an embryo that has had it's original genetic material removed Good Essays words 2.

Should Cloning be allowed to continue.

Cloning The First Human - Spark

In the 's, scientists discovered that strands of DNA could be cut using special enzymes, which could cut out genetic combinations. DNA contains information about genes particular organisms hold. Duplicates of genes are also possible through genetic engineering and are very useful for medical purposes. Advances in technology have raised issues such as animal and human cloning Free Essays words 3.

As with any new technology, ethical and moral ideals have clashed between those who support it and those who favor the opposing side. The dispute involves what to do with our ability to clone and manipulate DNA of human beings, plants, and animals, and whether it is ethical for us to pursue research and experiments with genetics or whether it is people just playing "God" Better Essays words 1.

Cloning defined as the process of making a genetically identical copy of an organism. The process consists of the artificial fertilization, with the identical genetic material, of a donor egg, followed by the placement of that egg into a surrogate uterus. Genetic modification is defined as any alteration of genetic material to make them capable of producing new substances or performing new functions, and consists of scientists editing the genes of a potential offspring in a lab in order to produce a better child Well it certainly has its high points.

There are amazing things to be had from cloning that range from spare organs for sick patients all the way to genetically cloned children for those who can bare none. While some things are frowned upon the benefits cannot be ignored. You could change the genetic makeup of a person and take away the things that hinder them like dyslexia or something more severe such as deformities Humans would be taking nature into their own hands. Over the past billion years, life has grown into a fascinating structure.

Of the , kinds of plants and more than a million kinds of animals that are known today, no two are exactly alike — yet within families there are marked similarities Monsanto From generation to generation family resemblance is so obvious that it is not thought about Good Essays words 3. Although his team of researchers had qualified to the public that it is unethical to clone humans1, the very prospect of being able to replicate creatures of our own kind is nevertheless enticing. Think of all the possible benefits that make many scientists prepared to cross those ethical boundaries: Firstly, couples who have tried a long time for identical twins, triplets or even quintuplets!

Better Essays words 2 pages Preview. For example, the seedless watermelon is a byproduct of genetic manipulation. Scientists use this practice is used in many labs all around the world, to create more advanced medicine and agricultural products. Every living thing contains DNA. Genetic manipulation can have great benefit to us if it is used in the correct manner, however it can also be used in manners which are morally wrong Did you know it took tries to finally create the first mammal clone, Dolly. The process of cloning is not even close to being perfected to be used on animals or humans.

It would also cause many different problems in the world if we did start cloning. We should stop this practice because it has to many flaws, it destroys individuality and uniqueness, will cause over population, and is against many religious and moral beliefs. Cloning started off with farmers cloning plants thousands of years ago in very simple ways, like cutting a plant and letting the roots combine to make another plant They are unique in the fact that we have never before had the technology to perform these acts.

We do not know the consequences of cloning a human being. We do not know the damage we can do by altering someone's genes. We do not know what disease we can cure. We do not know the limits of the evil we can unleash. Since we have not reached the full potential of the power we wield, we can only speculate on the outcomes of our actions Powerful Essays words 4 pages Preview.

Obviously the cloning of humans or the cloning of human cells is much different than the cloning of genetically superior livestock or a better quality, higher yielding food crop, and people throughout the world realize this. The cloning of human beings has become one of the worst fears in our society today and for that reason many laws have been passed throughout European countries and North America in an effort to ban human cloning Powerful Essays words 5. To do this, ethical decision making need to be made to decide whether to allow humans to be able to access these technologies.

Will these technologies interfere with the morals and principles of certain people and cause discrimination. Or will it result in a better human population that lives longer with less health problems and diseases. One of these technologies includes cloning which is also called somatic cell nuclear transfer Strong Essays words 4. This would be a future possibility if genetic engineering became more advanced. Through continued research in the field of genetics, techniques such as mapping genomes and splicing DNA can be used beneficially to improve on existing organisms and their traits.

To help understand genetic engineering, it is important to understand its history Animal cloning has advanced greatly since Hans Dreisch cloned the first ever animal in There are many different ways and reasons that animal cloning has been produced. The range of cloned animals vary from sea urchins, frogs, fish, salamanders, mice all the way up to sheep, cows and even dogs and cats. There are a few different ways cloning is done with animals. Strong Essays words 3. Human cloning is the asexual reproduction or replication of a human being at any stage of development.

It can also be defined as the formation of an identical genetic copy of a human being.

Cloning itself is not new as it dates back to the s where frogs and toads were experimented on. It is primarily divided into two types namely therapeutic cloning and reproductive cloning. Reproductive cloning is whereby there is a creation of a child whereas therapeutic cloning is the creation of stem cells that are used to replace damaged tissues Cloning is not yet approved for humans in the United States of America as a genetic reproduction created by scientists, since it is a complex experimentation but I agree with it being approve.

As a definition we can say that cloning is the act an asexual reproduction perfectly done with an example of DNA in the physiological and biochemical experiment with an original cell The general idea of clones may bring to mind an image of two symmetrical organisms. Nevertheless the identical features would only consist in the corresponding nuclear genes. On the fifth of July of Cloning had its turning point. The announcement by Ian Wilmut, Keith Campbell and his colleagues revolutionized medical-and-scientific history As a consequence of the nature of researching upon the biological infrastructure of living things, genetic engineering has gathered quite a strong opposing unit of common people and scientists alike, all concerned with the ethical complications of tampering with the nature of DNA to satisfy both human curiosity and advanc The solution to the possibility of rejection is to produce stem cells from the donor itself.

These stem cells can then be used to develop organs or tissues needed by the patient. There are over , people currently waiting for an organ transplant, and eighteen people will die each day waiting for an organ Why Organ. The overwhelming majority of the lucky patients that do receive an organ transplant in time must undergo immunosuppressive therapy that can have serious side effects. The cloned tissue would be compatible without the infectious risks of xenotransplants, or transplants between species Term Papers words 5. We have taken plant stems or part of its root and developed those parts into separate but genetically identical plants.

These methods of cloning are not seen as strange because its simple and widespread usage. In fact, many vegetables and fruits are grown using these cloning methods to produce an offspring identical to an exceptional plant. However, cloning, which started as a farming method, has now become a major source of debate due to breakthroughs in genetics You might shock with the truth and could not accept the truth. If human cloning be allowed, these researches will happen more frequently. Although some scientists and ethicists agree with human cloning, there are more evidence that human cloning yields negative results There has been many deliberations on weither cloning is ethically or morally right or wrong.

The definition of cloning can differ from one situation to another, in general when speaking about a cloneit means a fragment of DNA which is a serie of manipulations from a particular piece that can be generated unlimitedly Cullis, "Entering The Clone Zone. One branch of genetic research that shrouded in mystery is the ever-growing field of genetic cloning; reproductive cloning being one that contains a great deal of interest. This field of research is highly controversial, as one would expect. One side of the argument is that this will allow for us to stop species from going extinct or bring back extinct species, while the other side argues that this could be a gate-way to human cloning Some scientific practices, however, are shunned due to the practices being labeled immoral and unethical.

One such field of study would be genetic engineering, which is considered taboo by many scientific officials, and also has certain aspects that are illegal in many parts of the world. For those who do not know, the basis of genetic engineering is the understanding of DNA in an organism, and manipulating the genetic material to rid the organism of damaging genes and promote the growth of beneficial genes in offspring It was simply a fictitious fantasy that proved to only be for entertainment purposes. However, while all those novels and films were being produced, a multitude of scientists attempted to make what society thought of as a dream, into a reality.

The science of cloning is the process of making genetic duplicate of an organism. The scientific history of cloning spans more than years dating back to , and still going strong today This means to reproduce or propagate asexually and some sexually. Cloning is made when you have several embryos and you try to duplicate them to produce more eggs which is called SCNT. SCNT Somatic Cell Nuclear Transfer is used so that they can take a piece of DNA from an egg and transfer it to another egg after the nucleus has been eliminated by an ultra violet beam This issue has been a hot topic for the past decade after Dolly the sheep was cloning in Scotland.

Dolly was the first cloned mammal, whose very existence created much heat in the general public Hansen, Many people believe that cloning is ethically immoral and should never be done, but others think that scientific advances can greatly cure diseases. Michael Soules, a professor and director of the Division of Reproductive Endocrinology and Infertility at the University of Washington, concurs with the idea that reproductive human cloning is unethical Have you ever read an article about gene splicing or transgenic animals. All of these are examples of animal biotechnology and the results of different experimentations in that field.

But what exactly is animal biotechnology. Strong Essays words 3 pages Preview. Every single bit of their DNA is the same. For many people they first heard of cloning was when Dolly the Sheep showed up right around the year of Artificial cloning technologies have been around for much longer than Dolly, though.

There are three types of cloning: gene cloning, reproductive cloning, and therapeutic cloning. Gene cloning is essentially recombinant DNA technology, where a piece of foreign DNA is inserted into a vector, which can be copied by a host cell The cloning of human tissue should be allowed because the fields of medicine benefit from it; however, the full cloning of humans is a mockery of life because it creates a population of people who will not evolve or adapt to changes in the environment.

Therefore, the government should financially support the research of therapeutic cloning while condemning the act of reproductive human cloning After the first cloned sheep dolly was created, many people were keen in knowing more about cloning and its benefit to society.

Additionally, many of us want to know the pros and con the disadvantages and possible risks it may have on society and mankind.

These types of cloning are all ways of scientists trying to find ways to produce a living organism or organs If you had an illness like diabetes, have you ever wondered what it would be like if you did not.

    Cloning is the creation of an organism that is an exact genetic copy of another. The first successful clone was in when scientist Edinburgh cloned Dolly the sheep. She was the first animal to be cloned with an adult somatic cell by using the process of nuclear transfer. She was born on July 5 , lived to the age of six and died after being diagnosed with lung disease called Jaagsiekte The copied material, which has the same genetic makeup as the original, is referred to as a clone NHGRI, Gene experimentation is the deliberate modification of an organism through the alternation of its genetic code Catalano, Though cloning and gene experimentation are not exactly the same, they have the same basis.

    Gene experimentation, and cloning of humans and animals have gone on for centuries Better Essays words 5. On a greater scale, it can result in the production of an individual that is genetically identical to another organism, whether it is a plant, animal, or human. This is known as reproductive cloning Naik.

    The successful cloning of animals within the past few decades has indicated that there is a possibility for human cloning in the near future, and many consider cloning to be the future of stem cell research "Human Cloning" Better Essays words 4 pages Preview. Also named artificial selection humans have have used the principles of natural selection to help then take control of the breeding process to produce an offspring with a more desired trait. Selective breeding or artificial selection involves breeding a specific organism based on a specific phenotypic trait so that the desired trait is passed on to the next generation Free Essays words 2.

    You may be able to do that in the near future with cloning. Cloning is when an organism is genetically identical to the individual from which it was asexually derived Random House. Cloning was brought to light in when scientists successfully cloned a sheep. The birth of Dolly was a major scientific breakthrough. In writing this paper, I hope to shed light on what cloning is, the reasons to conduct cloning research, pros and cons of cloning, and what the future of cloning looks like Other desired characteristics with regards to the Human genome project scientists have had a breakthrough in science.

    Now scientists are able to create synthetic organs for transplants and prevent disease by manipulating genes. However, one major scientific innovation seemed to do the exact opposite. As the news of a cloned mammal spread nationwide the opposition to cloning was almost instant, perhaps too instant. The hasty reaction of an overwhelming portion of the population indicates that an already existing ideology towards cloning had developed even before cloning was achieved So far, the process of cloning has really only extended to the cloning of animals.

    Unfortunately, the results for animal cloning have been mostly unsuccessful, producing a very high failure rate, and leaving no hope for human cloning.
