QUESTION 1: Each minute, 300 million of your body cells die!!! (Don't worry - these cells are replaced by mitosis, or you would be dead in a very short time!) However, some of the body's cells last for years, and some divide every day. List three types of cells in your body you would think would be replaced frequently. List 2 types of cells you think would be replaced slowly, if at all.
QUESTION 2: A protein called "p53" normally functions to find damaged DNA in the nucleus. p53 prevents cells from going through mitosis until the DNA damage can be repaired. However, smoking cigarettes frequently causes mutations in p53 in lung cells. How do think this might play a factor in the development of lung cancer?
QUESTION 3: Why do you think chemotherapy drugs, which are given to fight cancer, cause a person's hair to fall out?
QUESTION 4: Totally Optional: Comments or questions?
