Cloning
In 1997, when the world first heard about Dolly the sheep, the first mammal to be cloned from an adult, the possibility of cloning a human moved from science fiction into the realm of reality. Now Congress is taking up the question of whether human cloning should be allowed. There are many pros and cons to this issue, but the benefits certainly outweigh the concerns regarding people's feelings against cloning.
It is now believed that it might be easier to clone humans than was previously believed. According to research at Duke University (Gorman, 2001), people have a genetic quirk that might prevent some of the developmental deformities associated with animal cloning. The mechanics in making a clone involve scientists to first take an egg and remove all of its genetic material. Then the nucleus of a cell is taken from the individual to be cloned and inserted into the egg. The cell is then given a jolt of electricity to activate cell division, basically tricking the cell into doing what a fertilized egg would normally do.
Then the embryo is implanted into a surrogate who carries it to term.
