Kinetochores are protein structures located at the centromere of chromosomes. They play a crucial role during cell division, specifically in the processes of mitosis and meiosis. Kinetochores serve as attachment points for microtubules, which are part of the spindle apparatus that helps segregate chromosomes into daughter cells. During cell division, kinetochores ensure that each daughter cell receives the correct number of chromosomes. They facilitate the movement of chromosomes by connecting to the spindle fibers and pulling the chromosomes apart. This precise action is essential for maintaining genetic stability in organisms.
