Mitosis
division of the nucleus
Mitosis is the process by which a cell divides its nucleus and genetic material into two identical daughter cells. The steps of mitosis are interphase, prophase, metaphase, anaphase, and telophase.
During the interphase, the cell is preparing to divide. The DNA is replicated, and the cell grows in size.
During prophase, the chromatin condenses into chromosomes, and the nuclear membrane and nucleolus break down. Centrioles move to opposite poles of the cell, and spindle fibers begin to form.
During metaphase, the chromosomes align in the middle of the cell, and spindle fibers from opposite poles attach to each sister chromatid.
During anaphase, the spindle fibers pull the sister chromatids apart to opposite poles of the cell, creating two complete sets of chromosomes.
During telophase, the nuclear membrane and nucleolus reform around each set of chromosomes, and the spindle fibers disappear. The cell then undergoes cytokinesis, dividing the cytoplasm and creating two identical daughter cells.
Mitosis is important for growth, repair, and asexual reproduction in organisms.
