WebAug 7, 2024 · Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate. The kinetochore spindle fibers shorten, allowing for 46 of the newly- freed chromatids to be dragged to one end of the cell and the remaining 46 chromatids to be dragged to the opposite end of the cell. WebSee Answer Question: The drug taxol stabilizes microtubules so they cannot shorten. 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.
