The chromosomes are then paired up and evenly split between the two resulting cells. But sometimes when cells—especially cancer cells—divide, the chromosome pairs separate unevenly, leaving one cell with more chromosomes than the other.

WebAug 1, 2009 · When cells are exposed to an anti-mitotic agent such as taxol, they arrest in mitosis due to chronic activation of the spindle-assembly checkpoint. They then undergo one of several fates. Cells might die directly in mitosis, or divide unequally to produce aneuploid daughter cells. Alternatively, cells might exit mitosis without undergoing division. WebDrugs called mitotic inhibitors stop cancer cells from making more copies of themselves.
