Answer:
To make a clone, scientists transfer the DNA from an animal's somatic cell into an egg cell that has had its nucleus and DNA removed. The egg develops into an embryo that contains the same genes as the cell donor. Then the embryo is implanted into an adult female's uterus to growCloning of human cells is a technology that holds the potential to cure many diseases and provide a source of exactly matched transplant tissues and organs. One cloning technology that has been developed for mammalian and human cells is somatic cell nuclear transfer (SCNT).
