What is cloning?
The Cloning is the making of an organism genetically identical to another by means of genetic engineering.
The foundation of cloning is the nucleus transplantation technology. The nucleus from a cell is extracted, usually from an embryonic (not differentiated) cell and this nucleus is inserted into a previously enucleated reproductive cell (in general an egg cell); the egg is then implanted in the organ where the embryonic development will take place. If the embryonic development occurs the new organism will have identical genetic patrimony to the organism owner of the cell whose nucleus was used in the transplantation.
