What Are The Components Of The Mitotic Spindle? The mitotic spindle is a special device essential for chromosome segregation ( mitosis) during cell division. It consists of three parts, chromosomes, two asters and a spindle region (Fig. 1). The overall shape of the mitotic spindle is due to microtubules, which are made of α and
At Which End Do Kinetochore Microtubules Shorten? During poleward movement of the autosomes in anaphase, the bundled region shortens by about 0.25 microm for each 1 microm the chromosome moves poleward; this suggests that, during anaphase, 75% of the kinetochore microtubule shortening occurs at the pole end. What end of microtubules do Kinetochores bind to?
Where Do Spindle Fibers Attach To The Chromosomes? The spindle fibers from the other side of the cell attach to the other sister chromatids of the chromosome. They attach at a point called the kinetochore, which is a disk or protein that is on each side of the centromere. The spindle fibers will move the
