Then there is artificial cloning. This cloning process involves cloning that would not normally take place naturally on the Earth. This is part of one the reasons why cloning is debated. The fact that it would be of man's creation and not nature's creation. Cloning is the technique of producing a genetically identical duplicate of an organism by replacing the nucleus of an unfertilized ovum with the nucleus of a body cell from the organism.
Scientists carefully pull out the nucleus of the egg which contained all the genetic information.
At this point in time, the egg has no genetic information and is basically a 'blank'. If sperm was ever added to that 'blank', nothing would happen because the egg is now a house with nobody home. After the cell is fused to the egg, it is given a little shock treatment and the cells inside the egg start to multiply using the foreign genetic information as its own. From then on, the egg will grow and become an exact copy of the original organism. There are many good thing that can come about because of cloning.
