Most people assume that cloning refers only to a whole organism, or reproductive cloning. Explain how therapeutic cloning is different from reproductive cloning
What will be an ideal response?
Whereas reproductive cloning is used to create a new individual, therapeutic cloning is not. In therapeutic cloning, the nucleus from an individual would be placed into an egg from which the nucleus was previously removed to create an embryo. This embryo would divide in order to produce stem cells. Those cells would then be removed and coerced to differentiate into a specific type of cell (and not into a new organism), which would be transplanted into a patient. The transplanted cells are used to replace faulty cells.
