Reproductive Cloning and Therapeutic Cloning

Reproductive Cloning
Reproductive Cloning is used to create an animal that has the same nuclear DNA as another existing or previously existing animal. Scientists transferred genetic material from the nucleus of a donor adult cell to an egg with out a nucleus. Meaning the egg has no genetic material. The egg that now contains the DNA from the donor then gets chemicals added to help the cell division. After all that is done and the cell has reached the right stage and will be put to the uterus of a female host who will carry until birth.  


Therapeutic Cloning
Therapeutic cloning is also called "embryo cloning" and it is used not to create and clone humans but to produce stem cells. The Stem cells are used to study the human development and to treat diseases. The cells are able to create any type of cell in the body. This method is a lot like the Somatic Cell Nuclear Transfer method. This method creates tissues and organs for the body instead of humans. The process of Therapeutic Cloning is to take healthy cells from patient and make many copies of them that can be used to match transplants or to repair damaged or diseased tissues and organs.
