Cloning , the process of generating a genetically identical copy of a cell or an organism.

The pros and cons of human therapeutic cloning in the public debate.

Dolly the sheep, the first mammal cloned from a somatic body cell, came into the world innocent as a lamb. However, soon after the announcement of her birth in February Wilmut et al. An important, and for many people troubling question arose: if the cloning of sheep is possible, will scientists soon start cloning humans as well; and if they did, would this be wrong or unwise? She represented a first undesirable and dangerous step to applying reproductive cloning in humans, something that many agreed should never be done. Only a small minority thought it was permissible, or even morally obligatory to conduct further research into human reproductive cloning. Some had no strong objections to it, but did not see any reason to promote it either. Dolly is now stuffed and set up for display in the National Museum of Scotland.

Society is much more relaxed about the idea of cloning plants when compared to cloning animals. Some people see this technology as way to mimic natural processes since an identical twin is essentially a clone that happens thorough natural reproductive methods. Dolly the Sheep was a successful experiment because scientists found that they could produce offspring from an undifferentiated cell through nuclear transfer. We have used this method to improve the animal cloning processes for other species, but the cost of following this process for commercial purposes is still way too high. When we examine the advantages and disadvantages of cloning animals, we must balance the need to push evolution along while still providing diversity in genetic structures. We already know that entire monocrops get wiped out when disease impacts agriculture, so the same outcome is quite likely when we take the same approach with the animal kingdom. Cloning animals would allow us to balance environmental habitats.

I think nobody can afford to ignore the progress that is made in science today. Scientific research gives us knowledge about things that nobody ever thought about just a few years ago, for example the cloning of humans. In this essay I want to focus on this topic with special regard to the advantages and disadvantages and the social and ethical problems. I will start with a definition of cloning. The next part of the essay will be about the beginning of life followed by a listing of arguments about advantages and disadvantages of human cloning. Furthermore my essay will involve a look on cloning and sciene fiction and finish with the economic reasons for cloning humans.

Human cloning is the creation of a genetically identical copy or clone of a human. The term is generally used to refer to artificial human cloning, which is the reproduction of human cells and tissue. It does not refer to the natural conception and delivery of identical twins. The possibility of person cloning has raised controversies. These ethical concerns have prompted several nations to pass laws regarding human cloning and its legality. Two commonly discussed types of theoretical human cloning are therapeutic cloning and reproductive cloning. Two common methods of therapeutic cloning that are being researched are somatic-cell nuclear transfer and more recently pluripotent stem cell induction.

Human Cloning

Handbook of Global Bioethics pp Cite as. This chapter covers the technical, philosophical, and juridical aspects of international governance of human reproductive cloning. Human reproductive cloning is the creation of a human embryo from a nuclear DNA sequence of an existing human being or from one having existed earlier in order to implant it into a womb, leading eventually to the birth of an identical human being. The methods available for cloning are developing quickly, and first the principal technical approaches to this issue are described.

As far as anyone really knows, scientists have yet to clone a human being, and there are no federal laws against it in the United State. However, seven states prohibit it altogether, and 10 states only allow it for biomedical research. While more than 30 countries formally ban cloning for reproductive purposes, China, England, Israel, Singapore and Sweden do allow cloning for research, but disallow reproductive cloning.

Scientists around the world continue to argue the advantages of cloning in hopes of being able to research it more thoroughly, but more than 30 countries have already issued bans on human reproductive cloning.
