Question

Quizplus · Accepted Answer

Taxol prevents microtubule depolymerisation, which interferes with the formation and function of the mitotic spindle. The mitotic spindle is responsible for separating chromosomes during mitosis, and without a functional spindle, mitosis cannot proceed properly. Taxol does not directly affect cytokinesis, centriole duplication, or chromosome condensation.
