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. WebTwo separate classes of movements occur during anaphase. 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?

During anaphase where do microtubules shorten

Did you know?

WebMore specifically, in the first part of anaphase — sometimes called anaphase A — the kinetochore microtubules shorten and draw the chromosomes toward the spindle poles. WebDuring anaphase A, the chromosomes move to the poles and kinetochore fiber microtubules shorten; during anaphase B, the spindle poles move apart as interpolar microtubules elongate and slide past one another. Many cells undergo both anaphase A and B motions, but, in some cases, one or the other motion dominates.
