Mysteries of Cloning

Cloning is creation of a exact replica of something. Plants can be cloned quite easily, by breaking of a branch or stem and planting it in the ground, and an exact replica of that plant will be grown. Human and animal cloning is not so easy. You need to take the egg cell of a to-be person and take out the nucleus. Then you get another cell that is whole and not damaged from any other person, then place it into the empty egg cell. Then place the egg cell back and it will grow into and exact replica of the person the nucleus from.
Here is a diagram that explains it more.
