Problem Set 4 BILD1 FA 2009 1. MITOSIS PROBLEM (a) Draw a picture of a diploid cell that has a genome consisting of TWO chromosomes called Chr1 and Chr2. (hint: since it is DIPLOID it will have two copies of Chr1 and two copies of Chr2) (b) Draw a picture of your cell with its chromosomes through the 4 stages of mitosis: prophase, metaphase, anaphase, telophase. At the end you should have two diploid cells. (c) Are these two cells you have created genetically identical? (d) Go back to your drawing in part B and on the metaphase diagram, label the metaphase plate, the centromeres, the centrosomes, the telomeres, the spindle. (e) Which cytoskeleton proteins are involved insetting up the spindle? Which are involved in cytokinesis? Where is the kinetochore? Which cytoskeletal component associates with the kinetochore? (f) What would happen during mitosis if the centromere was deleted from a chromosome?
