Mitosis: WarmUp 6

This week we will be investigating how eukaryotic somatic cells divide during the process of mitosis. The end result of this process is the creation of two genetically identical (clones) cells. This result is much different than what happens during meiosis. Meiosis involves the formation of gametes (sperm or oocytes) which are genetically different from the parent cell from which they originated.

Please identify and describe yourself:

Approximately 18 trillion of your body cells die each hour. Fortunately, these cells are replaced by mitosis (think about what would happen if they weren't replaced!). Some of our body's cells may last for years, and some divide on a daily basis. List 3 types of cells in the human body that you think would be replaced frequently, and then list 2 types of cells you think would be replaced slowly, if at all. Please explain your reasoning for selecting each cell type. Do not simply list 5 cell types!
Certain chemotherapy drugs cause a patient to lose their hair. Explain why this may occur.
Why do cells undergoing mitosis go through one set of cell divisions while meiotic cells undergo two sets?
WHAT'S YOUR OPINION? (I will not discuss individual responses in class): What did you think of the exam? Was it fair in terms of what was covered in class? Were there any "surprises"? Let me know what you think.
