    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) the fibers of the mitotic spindle. 

    B) anaphase. 

    C) formation of the centrioles. 

    D) chromatid assembly. 

    E) the S phase of the cell cycle. 



    A) the fibers of the mitotic spindle.
