Taxol is an anticancer drug extracted from the Pacific yew tree. In animal cells, Taxol disrupts microtubule formation by binding to microtubules and accelerating their assembly from the protein precursor tubulin. Surprisingly, this stops mitosis. Specifically, Taxol must affect

A) chromatid assembly.

B) the fibers of the mitotic spindle.

C) anaphase.

D) the S phase of the cell cycle.

E) formation of the centrioles.

Jonas Nguyen · Answer 1

The correct answer is B) the fibers of the mitotic spindle.

Explanation:

The Taxol avoids the mitotic spindle to form, affecting directly the fibers of it. This, therefore, will stop the mitosis process, as the microtubules won't be forming properly.
