Mitosis Homework Name: _______________________ 1. Draw the phases of the Cell Cycle below. Include: Interphase, prophase, metaphase, anaphase, telophase, and cytokinesis 2. Answer questions #1-4 on page 249 (“Analyzing Data: Life Spans of Human Cells”) 1. _____________________________________________________________________ 2.______________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ 3.______________________________________________________________________ ________________________________________________________________________ 4.______________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ 3. Choose one of the following scenarios to write about (answer on back): A: Suppose you were small enough to hitch a ride on a chromosome located in a plant cell that goes through mitosis and cytokinesis. Describe what you would see happening during each phase of the process. (Label your phases as you go.) B: Imagine that you are developing a drug that will inhibit the growth of cancer cells. Use your knowledge of the cell cycle to describe how the drug would target and prevent the multiplication of cancer cells. (Suggestion: Use the Internet to compare your anticancer drug with those currently being used.) #3 Option: _____ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ 4.
