Reproductive cloning means the creation of a newborn human or other animal that is an exact duplication of an existing person 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 the uterus of a woman with the intent of it developing into a fetus and eventually a newborn whose DNA is identical to that of the original individual. This method has been used to clone a sheep. This method is also known as adult DNA cloning.
Therapeutic cloning is also called biomedical cloning, research cloning or somatic cell nuclear transfer. It means the creation of pre-embryos in order to extract their stem cells and create a human organ. It involves the process of somatic cell nuclear transfer in which the nucleus of a cell from a human patient's body is injected into a human ovum which has had its nucleus removed. The goal of therapeutic cloning is to obtain stem cells which can be developed into organs for transplant that have an identical DNA structure to the organ recipient. ...Show more
