The formation of microtubules is crucial for the formation of the spindle apparatus, which is responsible for the separation of the duplicated chromosomes during mitosis. Therefore, if a drug inhibits the formation of microtubules, the spindle apparatus would be unable to form, and cell division would be affected. Specifically, the cell would be unable to proceed beyond the prophase of mitosis or might undergo abnormal division with incomplete separation of chromosomes.
