During the first part of anaphase, the kinetochore microtubules shorten, and the chromosomes move toward the spindle poles. During the second part of anaphase, the spindle poles separate as the non-kinetochore microtubules move past each other. What happens to spindles in prophase? norfolk constabulary logo

If taxol were added during mitosis, what effect would you expect it to have? Spindle fibers would not be able to attach to kinetichore proteins. Daughter chromosomes would not migrate to opposite poles during anaphase. It would have no effect. Web1. During prophase, microtubules of the miotic spindle lenghten. 2.
