The possibility of human cloning, was finally established when Scottish scientists at Roslin Institute created the first animal clone using a sheep named "Dolly." Dolly created worldwide interest and concern because of ethical and scientific implications. This huge feat, which was the breakthrough of 1997, also generated uncertainty over the meaning of "cloning"; an umbrella term which is used by scientists to describe different processes for duplicating biological material. This raises an important question: what exactly is cloning? Cloning is the creation of an organism that is an exact genetic copy of another. Every bit of DNA is the same between the two. There are different types of cloning however, and cloning technologies can be used for other purposes other then producing the genetic twin of another organism. The following three types of cloning will be discussed: reproductive cloning, therapeutic cloning, and embryo cloning, also the risks of cloning...
