This is an on-line version of the same Content Review questions included at the end of the chapter in your textbook. Use this version to quickly and easily submit your work to your instructor or teaching assistant.

1. What do restriction enzymes do?

2. What is a plasmid?

3. Once the gene that causes Huntington’s disease was found, researchers introduced the defective allele into mice to create an animal model of Huntington’s disease. Why was this valuable?

4. To begin the hunt for the human growth hormone gene, researchers created a cDNA library from cells in the pituitary gland. What did this library contain?

5. If a trait tends to skip a generation before it appears again in a pedigree, and if it occurs about equally often in males and females, what is its most likely pattern of inheritance?

6. What does it mean to say that a genetic marker and a disease gene are closely linked?
