BASIC PRINCIPLE OF REPRODUCTIVE CLONING

• First take mature somatic cells, that is cells other than reproductive cell such as skin cells, from the animal to be cloned.

•  Next, an unfertilized egg from an adult female of the same species is extracted and remove the nucleus.

• Then, the skin cell fuse with the egg with application of electric pulse.

•  The fused cell, which contains the skin cell’s nucleus, divides and forms an early-stage embryo.

• This embryo is implanted in the uterus of another female animal, called asurrogate mother, and allowed to develop.

• The surrogate mother then gives birth to an animal that is genetically identical to the adult that donated the skin cells.

• This newborn animal is referred to as a clone.
