The component of the cell cycle that leads to cell division is called mitosis. Mitosis is the process by which a single cell divides to produce two genetically identical daughter cells, ensuring that each new cell receives an identical set of chromosomes. This phase is critical for growth, tissue repair, and asexual reproduction in single-celled organisms. Mitosis is preceded by the interphase, where the cell prepares for division, but the actual division occurs during the mitotic phase.
