Connect! What is a “clone”? Would you want to be cloned? How could cloning be useful?

3. Cloning: Clones are genetically identical copies; bacteria that are genetically engineered reproduce quickly and asexually, thus producing many clones

many plants can be cloned from a part of an original plant cloning has also been done in animals; the most famous cloned animal is Dolly the sheep

scientists insert the nucleus of a normal (2n) body cell into an egg cell stripped of its nucleus which will develop into an embryo

A B C Another example of cloning…

Chunk… What is a clone? The cloned lamb is identical to which sheep, A, B, or C? Explain the steps in cloning Dolly. Why would researchers want a population of cloned lab mice? What is the risk of having an entire population of clones? What is wrong in the science in this cartoon?

Explain the cartoon above. How could cloning be used to save endangered species? Hypothesize…
