Cloning: The Benefits and Where to Draw the Line Essays

As mentioned earlier, cloning is the copying of an organism that results in identical offspring (“Cloning”). Scientists have tried cloning many times on frogs and other organisms (“Cloning”), but when the first mammal to be cloned was successful in 1997, scientists jumped into pools of thoughts to clone humans. The first mammal to be cloned was a sheep named Dolly. The process of cloning Dolly was called Somatic Cell Nuclear Transfer. The nucleus of a somatic stem cell is taken out of the eggs of the

As mentioned earlier Dolly is the most famous of the cloned organisms, but there were many before and after her. In 1952 a tadpole was cloned, the first clone ever. (Human Genome Project) Dolly was the first mammal ever cloned. After Dolly other animals such as sheep, goats, cows, mice, pigs, cats, rabbits, and a guar have been cloned. Some animals are more resistant to the procedure used for cloning. The process used is called somatic cell nuclear transfer. This process is used to create an animal that has the same nuclear DNA as another animal. They are not identical in the strictest sense the mitochondria and mitochondrial DNA comes from the egg. The “acquired mutations found in the mitochondrial DNA are believed to play an important role in the aging process.”(Human Genome Project) The process starts by removing all the genetic information from an unfertilized egg with an extremely small needle. Then an adult cell is taken from the donor. The genetic material is removed from the cell and implanted in the now empty embryo. Then the cell is treated with chemicals or an electric current to cause it to start to divide. Once it reaches a certain size it is implanted into a host uterus where it

For what purpose animals such as frog, mouse or sheep need to be clone? To what extend these organisms are able to use for cloning? Some people may wonder whether cloned organisms exist or not after watching live action movies, animes or cartoons that consist of cloned characters. The answer for this question is yes, clones do exist. The term, cloning is a process of producing genetic identical living organism asexually using genetic material such as DNA. A cloned organism is likely to have the identical gene with the parents. There are several types of cloning such as therapeutic, reproductive and embryonic cloning. These steps are performed by expert scientist with the aid of modern technology. The first experiment on cloning was carried

Cloning: is it the future of medicine and the curing of diseases or is it the beginning of an unholy tragedy? Cloning needs to be looked into for the fact it could help save many people 's lives. Before I decided to study the subject I had no idea how much cloning could help us as the human race. Cloning is a very promising field of study and could hold the key to the future of what it means to be human.

The first idea of cloning began in 1938, when scientist Hans Spemann had the idea to replace the nucleus of an egg with the nucleus of another cell. Mr. Spemann did this in an attempt to grow a new embryo; however, the experiment was unsuccessful (Copernicus Science Centre). A successful attempt in the field of cloning did not occur until the 1970’s when Scientist John B. Gurdon successfully cloned a frog. However, each clone did not survive passed the stage of a tadpole. Scientist Gurdon was questioned by the public as to whether or not his practices were morally and ethically correct, especially since he was unable to successfully clone a mammal. (Copernicus Science Centre). The cloning of a mammal was not successful until 1997 when the

Therapeutic cloning has many medical opportunities that will continue to be investigated for years into the future (Nash, Age of Cloning).

“Many people first heard of cloning when Dolly the Sheep showed up on the scene in 1997. Artificial cloning technologies have been around for much longer than Dolly, though. There are two ways to make an exact genetic copy of an organism in a lab: artificial embryo twinning and somatic cell nuclear transfer.” (Genetic Science Learning Center) This type of cloning has to do with organisms; so either human or animal. These techniques are done to produce twins. Though the techniques vary, they both are done to receive the same result. The type of cloning used to create Dolly the Sheep is Somatic Cell Nuclear Transfer, also known as nuclear transfer or therapeutic cloning. “What makes dolly so special is that she was an exact genetic

The process of cloning is a timely and delicate process that has many pros and cons. When a scientist clones an organism, it is as if he is taking life into his own hands and

Genetic cloning involves the replication of an organism’s DNA which may then be put into another cell to create a clone of the organism in which the DNA was taken from. Cloning technology has been evolving for over 100 years and during this time has caused mass intrigue and controversy. This is mainly due to the fact that the cloning of humans is a very real

In order to be able to understand one needs to know the process of cloning involves. Although, there have been many proposed methods for cloning, only one of them has been successful so far. Put simply, cloning is the process in which the DNA of a female egg cell is replaced with different DNA from another cell. This technique is also called “Nuclear Transfer” or “Nuclear

Nowadays, in the twenty-first century, advances in medical sciences are being more and more common. As people become sicker, scientist try to find the way to solve that prob-lem. There are many series of medicaments, surgeries, and machines that have been develop to satisfy the necessities of modern society. However, all these techniques and options are not enough to cure many diseases or other types of problems such as amputations, transplants, and so on. As a result, scientists try to develop human cloning.

Cloning is said to have begun in 1885, when Dreisch separated an embryo of a sea urchin and made two complete sea urchins. Genetic modifications continued to grow. In 1952, Robert Briggs and Thomas King shifted the nucleus from a tadpole embryo into a frog egg in which the nucleus had been removed. This was the first noted successful nuclear transfer. In 1987, three people, Neal First, Randal Prather, and Willard Eyestone, cloned cows using nuclear transfer from embryonic cell. As time went on, scientist figured out how to use nuclear transfer from laboratory cells to clone sheep in 1996. That same year the first mammal, a sheep they named Dolly, was created by somatic cell nuclear transfer. Ian Wilmut and Keith Campbell tried 277 times to produce an embryo, Dolly was the only one that was carried

If we’re talking about the actual physical cloning that exists in reality, not the kind shown in science fiction genre films and romanticized in comic books, then the process is much more different than one might expect. There is no magical machine in which one thing is put in and another or another two, come out. Firstly, let’s establish the things that we can clone. According to the National Human Genome Research Institute, essentially anything that has biological cells can be cloned. So no, we cannot simply clone your favourite pair of thousand dollar Kanye West sneakers. But anything that has genetic information and a biological makeup, can be cloned. This can range from plants to animals, to theoretically, even humans. Gene cloning, for instance, is a commonly practiced type of cloning where certain a certain gene or strand of DNA is replicated. The gene is taken from an organism that

On July 5, 1995 Dolly the sheep was the first successfully cloned mammal born from an adult cell, the cells that made the embryo that turned into Dolly were taken from two separate sheep a nucleus from a black face sheep and the other cell the nucleus was taken out was from a white face sheep .The united states animal cloning program has been in controversy for the past couple decades, bringing some concerns about multiple assets of this program. Animal cloning has been around since 1938 when Hans Spemann suggested that they conduct a “fantastic experiment” of taking the nucleus of an egg cell and replacing it with another nucleus to create an embryo. This kick-started a multi million dollar program which successfully cloned multiple animals from frogs to fruit flies, and pigs to primates. Some positive things animal cloning can do for mankind are: to de-extinct animals, quickly reproduce livestock for food sources, and they are used to find genetic testing and drug/disease research.

Whether for good or bad, scientists are gradually getting closer to figuring out new ways to clone a human. An uproar from citizens who believe cloning is unethical has led to government officials banning scientists from experimenting on, what could have been the biggest scientific discovery. Dolly the sheep, the first ever mammal to be cloned, had caused conflict among citizens and scientists. Dolly was cloned using the nuclear transfer process, where scientists remove the DNA from an unfertilized egg and inject the DNA into the nucleus. This simple, yet complicated, process took place in 1996 and the scientific world has come a long way since. Dolly the sheep may have been “the world’s most famous sheep”, but her creation has introduced many problems. As a result of Dolly the sheep, numerous laws were passed that banned cloning and deeming it unethical.
