Cloning In Organisms


Organism cloning (also called reproductive cloning) is a procedure of creating a new multi cellular or genetically identical to anther. This type of cloning is an asexual method of reproduction, where fertilization does not take place.
Dolly is am example of reproductive cloning. Dolly was created by reproductive cloning technology, in a process called "somatic cell nuclear transfer" (SCNT), scientists transfer genetic material from a nucleus of a donor adult cell to an egg whose nucleus, and thus it genetic material has been removed. The reconstructed egg containing the DNA from an adult must be treated with chemicals in order to stimulate cell division. Once the cloned embryo reaches a suitable stage, it is transferred to the uterus of a female host, where it continues to develop until birth.
