The anticancer drug paclitaxel (Taxol), derived from the Pacific Yew, has many effects on mitosis.  One of its most powerful effects is that it prevents disassembly of the mitotic spindle, which prevents spindle fibers from shortening.  Which phase of mitosis would this directly affect?  Why would this stop cell division overall and lead to cell death?
