What is the difference in transgenic organisms and cloning? Look at this diagram and compare it to the one you saw on transgenic animals.

Diagram show how a sheep is cloned. The nucleus of an egg is removed from a black-faced sheep. The nucleus is fused with a cell from a white faced sheep. The egg fused with the cell develops into an embryo and is implanted into a female sheep. Off spring is a white faced clone.”

In transgenic organism a piece of donor DNA is transferred into the recipient organism, while in cloning the entire nucleus (all DNA) is removed and placed in the donor organism.
