How does cloning work in de extinction? Cloning for de-extinction has centred primarily on the use of SCNT. SCNT entails the transfer of the nucleus from a somatic (body) cell of the animal to be cloned into the cytoplasm of an enucleated donor egg (an egg cell that came from another animal and that has had its own nucleus removed).
