The completion of spindle formation is a crucial transition point in the cell cycle called the spindle assembly checkpoint. If chromosomes are not properly attached to the mitotic spindle by the time of this checkpoint, the onset of anaphase will be delayed. Failure of this spindle assembly checkpoint can result in aneuploidy and may be involved in aging and the formation of cancer. thought of the day for hoteliersWitryna2 maj 2014 · Metrics.
