WebYou have cells with 46 chromosomes (somatic or body cells) and cells with 23 chromosomes (gamete or sex cells). Since you started as a single cell with 46 chromosomes, there must be two types of cell division taking place in your body to accommodate both somatic and gamete cells. Mitosis and meiosis are the two types of … 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 …
