Part 1: Genetic Testing
1. In 2003, Human Genome Project decoded the human genome. What is the human genome?
2. What is genetic testing?
3. Genetic testing does not cure diseases. So why would people want to get it done? List three different
reasons/examples.
4. What are two reasons that people would be against genetic testing?
Part 2: Gene Therapy
5. What is gene therapy?
6. How is germ line gene therapy different from somatic cell gene therapy?
7. How could gene therapy be used to help adults?
8. How could gene therapy to be used to help future generations of children?
9. Gene therapy could be used to cure Alzheimer’s, but not the common cold. Why?
10. What are two reasons that people would be against gene therapy?
Part 3: Stem Cells
11. What is a stem cell?
12. How can stem cells be used to help people?
13. What is in vitro fertilization (IVF)?
14. How do scientists obtain embryonic stem cells from IVF?
15. How do scientists obtain somatic (adult) stem cells?
16. Why do some people oppose (they are against) embryonic stem cell research?
17. Identify one disease/disorder that could be treated by stem cells. Then, describe HOW stem cells could be used
to treat that disease/disorder.
Part 4: Cloning
18. In the following list, circle each body part that contains DNA: saliva, urine, hair, a drop of blood, skin cells
19. When was Dolly cloned, and what species was she?
20. What are three reasons that we might want to clone animals?
21. Describe the FOUR major steps of somatic cell nuclear transfer (the laboratory technique for cloning cells)
22. How is cloning used to create embryonic stem cells?
Part 5: Situations
23. Imagine that we are 50 years in the future, where biotechnology is much more advanced than it is now. You were
born with a rare genetic disorder that caused your nervous system to develop improperly. As a result, you are
paralyzed. Scientists could have prevented your disorder through germ cell gene therapy: if they had altered the
genes in your parents’ sperm and eggs, you would be able to walk. However, in 2020 many religious groups
banded together and convinced Congress to outlaw gene therapy.
a. Write one paragraph explaining why you – the paralyzed person – might be in favor of gene therapy.
b. Write a second paragraph explaining why the religious groups oppose (are against) gene therapy.
c.
Write a third paragraph explaining which side you agree with, and why.
