kinetochore,xplain
- The kinetochore is the protein structure on chromatids where the spindle fibers attach during cell division to pull sister chromatids apart.
- During mitosis prophase stage, the chromatids held together, at the narrow region called centromere. At this region, each chromatid has a disc like kinetochore, where the spindle microtubules join it. The two kinetochores of the chromosome face in opposite directions attach to opposite poles of the mitotic spindle. Kinetochores start, control and supervise the striking movements of chromosomes during cell division.
