Understanding: The Power of Genes
Part One
1. Describe the first living being. About how long ago was this being alive?
2. Why is there so much variety in the world?
3. DNA is called the “silent witness”. Explain what you think this means.
4. Why was the Sam Shepard case so important? How did DNA contribute to this case?
5. The video speaks of a DNA “x-ray”. What is that x-ray called? What do the bands
represent?
6. What is CODIS?
7. Who is Dolly and why is she so important to genetics?
8. When cloning, why do they remove the nucleus of the egg cell?
9. What do you think is meant by “genetic engineering”?
10. What are transgenics?
11. What is the designer cow?
12. Why would transgenic pigs be useful?
13. What is cross species cloning?
14. How would cross species cloning be useful?
Part Two
1. Why is the study of Sharon and Debbie so significant?
2. What is the novelty seeking gene?
3. How many bases do humans have?
4. Why were the hairless mice so important in the alopecia study?
5. What is gene therapy?
Genetic engineering/genetic technology is very controversial. Cloning is only one aspect of
genetic engineering. This field makes it possible to perform in depth studies of genetic diseases
and their causes, as well as investigate possible cures. In addition, as presented in the movie, it
makes it possible to use animals to create necessary human proteins. However, this could also
make it possible for people to create “designer babies”, babies who have only the “good”
characteristics. Write at least 2 solid paragraphs (6-8 sentences each) about whether or not you
thing advancements in genetic engineering/technology will be beneficial to the world. You
MUST pick a position and provide at least 3 supporting pieces of information for your position!
