Taxol is an anticancer drug extracted from the Pacific yewtree. In animal cells, taxol disrupts microtubule formation bybinding to microtubules and accelerating their assembly from theprotein precursor, tubulin. Surprisingly, this stops mitosis.Specifically, taxol must affect

A) the fibers of the mitotic spindle.

B) anaphase.

C) formation of the centrioles.

D) chromatid assembly.

E) the S phase of the cell cycle.



Answer:

A) the fibers of the mitotic spindle.
