Kinetochores /kuh-NET-uh-kores/ The kinetochore is the structure where the spindle apparatus attaches to a chromatid during mitosis and meiosis. It is usually located in or near the centromere. When the spindle connects, several pole-to-chromosome microtubules ("kinetochore microtubules") attach to each single kinetochore. Each normal chromatid has one and only one kinetochore.
