Cloning is the production of one or more individual plants or animals (whole or in part) that are genetically identical to an original plant or animal.

This involves removing the DNA from an embryo and replacing it with the DNA from a cell removed from an individual. Then, the embryo would be implanted in a woman's womb and be allowed to develop in to a new human whose DNA is identical to that of the original individual. This method has been used to clone a sheep. Adult DNA cloning cannot ethically be used to produce a human clone, because experiments on animals have sometimes produced defective specimens.

Therapeutic cloning starts with the same procedure as is used in DNA cloning. The resultant embryo would be allowed to grow for perhaps 14 days. It's stem cells would then be extracted and encouraged to grow into a piece of human tissue or a complete human organ for transplant. The end result would not be a human being; it would be a replacement organ, or piece of nerve tissue, or quantity of skin. The first successful therapeutic cloning was accomplished in 2001-NOV by Advanced Cell Technology, a biotech company in Worcester, MA.
