BSL Biology Glossary - clone - definition

Definition: There are two ways of cloning. The first is to take the nucleus from a cell from an animal, for example a sheep, and put it into the cell of another sheep. This new cell goes into the uterus of the second sheep so she becomes pregnant. The lamb that is born is an exact genetic copy of the first sheep.

The second method is natural, like a flowering plant pollinates itself and produces seeds which will become identical copies of the original plant.
