We hear about it often, might sometimes think about it, but do we really understand it? The goal of this lab is to help you further understand what cloning is and isn't, as well as to understand some of the many social implications cloning can have, both good and bad.

Log on to: http://learn.genetics.utah.edu/content/tech/cloning/ and explore this module to find the answers to the questions below.

1. Compare and contrast the following methods of Cloning: Embryo Twinning and Somatic Cell Nuclear Transfer

2. How does Somatic Cell Nuclear Transfer (SCNT) differ from the natural way of making an embryo?

3. Briefly explain the medical reasons for cloning.

4. List reasons, other than medical, for cloning.

5. What was the first organism to be cloned? How was it done? In what year did this take place?

6. What was the first organism to be cloned using nuclear transfer?

7. How were the first cows cloned?

8. What organism helped prove that cloning could be done using cells from males (up to this point all cloning experiments had been carried out using cells from females)? What was the organism's name?

9. In what year was the first human clone created and what stage of development did it reach before it stopped growing?

10. Give at least two reasons why a clone might not necessarily be a carbon copy of the donor organism. Name the two animals (they are the same species) that serve as an example.

11. List and briefly explain the risks of cloning.

12. Choose two of the questions raised at the end of "What Are Some Issues In Cloning?" Write the questions and your responses to them below.
