The Spindle

The Spindle is a key structure within a cell that plays a crucial role during cell division, specifically mitosis and meiosis. It consists of a network of protein fibers called microtubules that help separate duplicated chromosomes into two new cells. As the cell prepares to divide, the spindle forms and attaches to the chromosomes at their centromeres. It then pulls the chromosomes apart, ensuring that each new cell receives the correct number of chromosomes. This process is vital for maintaining genetic stability and proper function in living organisms.
