Cloning Moral and Ethical Aspects.

Introduction

Cloning Moral and Ethical Aspects Introduction In 1997 a Scottish researcher, Ian Wilmut had successfully cloned an adult sheep. It took about three hundred tries to get it right and explicitly it appeared to be relatively simple in terms of technique and the used equipments. The initial public and professional response to the announcement of the new technique was one of concern. In some cases, these responses were mistaken of how this new technology may reshape our future. The source of these feelings was fear of the fact that this new technique would allow human cloning, and would allow for an unlimited number of genetically similarities. The birth of the cloned sheep "Dolly" is an illustration of the ethical responsibilities of the scientists toward their community where they live and serve and toward the public fear and anxiety that the scientific achievement provokes. I will examine some of the public and official responses, as well as some of the most important applications on human cloning, and the potential promises. There are two different techniques for cloning. The first one is by cell mass division or "embryo splitting", and the other one is by nuclear substitution, the technique used to create "Dolly". ...read more.

The cell taken from the cell biopsy will be destroyed afterwards, while the cell taken to create a clone may have the chance to develop and create a human being. Somatic cell transferring (Nuclear substitution) This technique is an extension of a research that is over 40 years old. This technique is based on the idea that nuclei from cells derived from and adult could be reprogrammed, or that the full genetic complement of such a cell could be reactivated well into the chronological life of the cell. This can be done by removing the nucleus of an egg cell and substituting a nucleus taken from the cell of another individual usually a cell from an adult. To date, there has been only a single reported case of cloning using this technique on a higher animal. That of course, was the reported "Dolly". The technique had been successful in only one of 277 attempts. The result has not been successfully reproduced anywhere in the world. So far the ability to use adult cells as donors in somatic cell nuclear transfer technology to produce a live-born cloned animal has not been proved. ...read more.

Conclusion

As any new discovery, it generated a widespread wave of fear at public level. The new technology brought a lot of promises but uncertainties. Mass meetings were held everywhere, the technique was applied quickly. How poor would the world be, if the rush of the lawmakers banned the recombinant DNA technology. Although cloning technology might seem controversial at present, in time it will be widely accepted by the public, once they see that the potential benefits of such a technology. The medical and research communities are not interested in cloning people, but are interested in producing cures for diseases and disabilities that affect our society, resulting in harmful emotional, and economic costs every year. Today, the cloning techniques on human cells, genes and tissue is critical to identifying cures, preventions and treatment for many diseases such as cancer, diabetes, Parkinson's and cardiovascular diseases. The potential for pharmaceutical production and the prospect for the regeneration and repair of human tissues is too great, it could mean saving the lives of countless people. The cloning of human embryos for the sake of producing cures and treatments should go forward, and so should the research that involves the cloning of animals and plants, for the sake of finding cures that could save human lives. Over all, human life, in any form, is the most important and valuable thing. ...read more.
