  1. There are two techniques for cloning adult cells. The first involves inserting an adult cell into an unfertilized egg after the egg's nucleus is removed. An electrical pulse causes the cells to fuse and develop into an embryo. The embryo is then transferred to the womb of a surrogate mother until birth.

    Another method for cloning adult cells is to extract the nucleus from an adult cell, and insert it into an egg cell without a nucleus. The cell is treated with a chemical that fuses the nucleus with the genetic material to the cell and an embryo develops. The embryo is transferred to the womb of a surrogate mother.
