Human Cloning Debate and Life Issues
The use of cloning to produce "Dolly" the sheep has prompted a public debate about cloning humans. This issue has quickly become linked with the issues of abortion and embryo research.
What is cloning?
Cloning is a way of producing a genetic twin of an organism, without sexual reproduction. The method used to produce Dolly the sheep is called "somatic cell nuclear transfer": the nucleus of a body cell ("somatic cell") is transferred into an unfertilized egg whose nucleus has been removed or rendered inactive. A tiny electric pulse may then stimulate development of the resulting embryo, which is an almost exact genetic twin of the creature that supplied the nucleus. It may be technically possible to use this procedure to reproduce human beings.
What does cloning have to do with embryo research?
A great deal. Cloning a human being or other large organism begins by artificially producing an embryo of that species. To produce one live sheep, "Dolly," scientists created 277 sheep embryos; 276 died or were discarded. Experiments in human cloning would involve the creation and destruction of human embryos on a massive scale.
