Cloning is the creation of an organism that is an exact genetic copy of another. There are a couple of ways to make an exact genetic copy of an organism: artificial embryo twinning and somatic cell nuclear transfer. Artificial embryo twinning is the relatively low-tech version of cloning and it mimics the natural process of creating identical twins. Somatic cell nuclear transfer, (SCNT) uses a different approach than artificial embryo twinning, but it produces the same result: an exact clone, or genetic copy, of an individual. What are the steps in SCNT? Order these steps so you can complete your own cloning project. A. Stimulate cell division B. Deliver baby C. Remove and discard the nucleus from the egg cell D. Isolate donor cells from egg donor and germ cell donor E. Transfer the somatic cell nucleus into the egg cell F. Implant embryo into a surrogate mother
