Taken from ActionBioscience.org http://www.actionbioscience.org/biotech/mcgee.html biotechnology:  cloning    Primer on Ethics and Human Cloning     By Glenn McGee     An ActionBioscience.org original article article highlights Before cloning is considered permissible medicine for human  infertility, society needs to resolve many questions, including: Is cloning unnatural self-engineering? Will failures, such as deformed offspring, be acceptable? Will cloning lead to designer babies who are denied an open  future? Who is socially responsible for cloned humans? Do clones have rights and legal protection? more  on author February 2001 Primer on Ethics and Human Cloning By Glenn McGee A clone's DNA is  exactly the same  as that of the  original  organism. Human somatic cell nuclear transfer, otherwise known (somewhat  inaccurately) as creating an embryo by "cloning," involves 1 : The starvation and subsequent implantation of DNA from specialized,  non-sexual cells of one organism (e.g., cells specialized to make that  organism's hair or milk) into an egg whose DNA nucleus has been  removed. The resulting egg and nucleus are shocked or chemically treated so  that the egg begins to behave as though fertilization has occurred,  resulting in the beginning of embryonic development of a second  organism containing the entire genetic code of the first organism. Mammalian cloning, through this nuclear transfer process, has resulted in the  birth of hundreds of organisms to date. However, significantly more nuclear  transfer generated embryos fail during pregnancy than would fail in sexual  reproduction, and a substantial majority of cloned animals who have survived

to birth have had some significant birth defect. Human cloning:  the most  controversial  debate of the  decade.  Reproduction, or perhaps more accurately, replication of an organism's DNA  identity does not normally occur in mammals, with the exception of twinning,  which always results in the simultaneous birth of siblings. Only plants  reproduce through replication from one generation to another. The prospect  of such replication for humans has resulted in the most controversial debate  about reproduction ever to be taken up in western civilization.

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
