WebChromosome segregation during mitosis requires a specialized structure called the mitotic spindle. The mitotic spindle is bipolar; the two ends of the spindle are called “poles” and define the spindle long axis. During chromosome segregation the sister chromatids are moved toward the spindle poles (Fig. 2 and Video 1).The major structural elements …
