Cloning of Endangered Animals What exactly is cloning? It is making an identical replica or a duplication of any kind, such as a piece of DNA or an individual cell. Clones are an exact genetic copies. There are different methods used when animals are cloned. Somatic Nuclear Transfer, where the nucleus is transferred from a somatic cell to an egg cell.
The point of cloning is that it can help a lot of people for medical purposes. Some people think we can have a farm for clones to harvest their organs. Scientist are more focusing on making the embryonic cells than anything else. Scientist have been working on how to clone animals that have become extinct, using the DNA tissue samples that they have gathered. In 2009, scientist had their first near-success cloning an extinct animal.
Another important advantage of cloning humans is for infertile couples. Cloning babies seems to be the perfect solution, although there are some ethical issues. By cloning babies for parents who can not have them on their own, you could create the “perfect” child. There are special genes that can be added to enhance some special talents, you could pick the sex of your baby, as well as test for hereditary diseases to choose whether or not to use that egg. Although that may seem like a good thing, the process of harvesting human eggs for donation is very painful, lengthy and increases health risks for the donor.
According to the National Human Genome Research Institute, scientists use therapeutic cloning to create stem cells with the same DNA by harvesting embryonic cells in their early development, ( Cloning Fact Sheet, 2017 ). As a result, cloned embryos in the test tubes are destroyed. Though therapeutic cloning can offer benefits to human health, gene(or DNA) cloning is a more efficient and preserved route to go. This is because gene cloning proposes close to the same benefits, and does not need the practice of cloning human embryos. DNA cloning can copy stem cells instead of extracting them from human embryos.
Human cloning can produce an exact copy of the person that it was cloned from, meaning that asexual reproduction can be possible in the near future. The idea of human cloning is becoming a nightmare as this wanton act is turning to a reality because it will take the beauty of life and the differences among each individual away. And it is argued that human cloning is against human rights because everyone should have the right to live as a unique individual being on this planet, and not just a industrial product to help infertile parents. Secondly, it gives the scientists the power “to play” god as the author states in this article, “Leaving the realm of fiction, cloning offers practical problems on several levels. First, there is the possibility that the animal or human clones may suffer additional medical problems.
This experiment has only 5% chance to get success. So the first argument against human cloning is straightforward and widely shared: it is dangerous. Here genetic screening is used with cloned human embryos and any embryo that does not pass will be killed. So the opponents of human cloning say that an embryo at any stage of development is a human life, worthy of protection and any kind of research that entails destroying an embryo is immoral, unethical, no matter how worthy the intent may be. It involves using human beings as means; it turns human into commodities and fosters a culture of
Introduction Today I’m going to talk about Therapeutic cloning. What is Therapeutic Cloning? Therapeutic Cloning is a technique in medical science that you can help people to get rid of some disease that they have. Scientist has already succeeded in the experiment on healing brain disease and Parkinson disease on mice. And they are working on heart disease.
Human reproductive cloning, if successful, will allow infertile couples to have a genetically related child. Identical sex couples can also have a child without the use of donor sperm or donor eggs, although the men would require a surrogate to carry the clone until birth. All of these are restricted by current medical advancements. However, before we can create a
Among discussing the history and vast progression of transgenesis and genetic research, Slonczewski addresses serious moral and political dilemmas relating to the extent humanity should be allowed to achieve in meddling with the creation of living organisms. Professor Leon Kass, an advisor for United States’ President Bush, was referenced in her analysis when Slonczewski asks “Why is cloning so bad? Kass speaks of the ‘narcissism of those who would clone themselves,’ and the ‘grotesqueness’ of those who would clone others” (Slonczeski). Dolly the lamb was disregarded as an accidental success, but since her creation, “all kinds of mammals have been cloned, including a monkey and twenty-four "perfect" cows” (Slonczewski). Cloning in the agricultural industry has aided both in the plant and animal domains.
