Mitosis is the process of cell division where the nucleus divides into two nuclei, each containing the same number of chromosomes as the original parent cell. During prophase, the chromatin condenses into distinct chromosomes, the nucleolus disappears, and the nuclear envelope breaks down. Chromosomes then align in the center of the cell before spindle fibers pull the identical sets of chromosomes to opposite ends of the cell during cell division. Errors during this process can lead to uncontrolled cell growth and the development of cancerous tumors.
