Question

Quizplus · Accepted Answer

During anaphase, the chromosomes are pulled towards opposite poles of the cell by the shortening of microtubules, specifically the kinetochore microtubules. If a drug prevents the shortening of microtubules, it would prevent the movement of the chromosomes and therefore affect anaphase.
