Textbook Question
Chapter 24, Problem 24.3PS
Chromosome Movement in Mitosis. It is possible to mark the microtubules of a spindle by photobleaching with a laser microbeam (Figure 24-29). When this is done, chromosomes move toward the bleached area during anaphase. Are the following statements consistent or inconsistent with this experimental result? In each case, explain your answer.
- (a) Microtubules move chromosomes solely by disassembling at the spindle poles.
- (b) Chromosomes move by disassembling microtubules at their kinetochore ends.
- (c) Chromosomes are moved along microtubules by a kinetochore motor protein that moves along the surface of the microtubule and “pulls” the chromosome with it.

- Dynamic instability causes microtubules either to grow or to shrink rapidly. Consider an individual microtubule that is in its shrinking phase. What would need to happen at the end of the microtubule in order for it to stop shrinking and to start growing again? Be specific!

For an actively proliferating cell, the average lifetime is 5 minutes in interphase and 15 seconds in mitosis. If the average length of a microtubule in interphase is 20 μm, how long will it be during mitosis, assuming that the rates of microtubule elongation due to the addition of tubulin subunits in the two phases are the same?arrow_forward
