The structure that organizes and pulls cells apart during cell division is the **mitotic spindle**. The mitotic spindle is a structure made up of microtubules and associated proteins. It plays a critical role during mitosis (the process of cell division) and meiosis (the process of creating gametes).
During cell division, the mitotic spindle forms between the two centrosomes as they move to opposite poles of the cell. The spindle fibers attach to the centromeres of chromosomes, aligning them in the center of the cell. Once all chromosomes are properly aligned and attached, the spindle fibers contract, pulling the sister chromatids apart towards opposite poles of the cell, ensuring that each daughter cell receives an identical set of chromosomes.
The coordinated action of the mitotic spindle is essential for proper cell division and the maintenance of genetic stability.
