Therapeutic cloning is the
process of creating multiple copies of a cell to treat a disease. In this type of cloning, the nucleus of a
cell, such as a skin cell, is inserted into a fertilized egg whose nucleus has
been removed. The nucleated egg begins to divide repeatedly to form a
blastocyst. Stem cells are then extracted from the blastocyst and they are used
to grow cells that are a perfect genetic match for the patient. The cells
created through therapeutic cloning can then be transplanted into the patient
to treat a disease from which the patient suffers.
