cell cycle and mitosis

• Mitosis is used for growth and repair of tissues.
• Mitosis involves only one division.
• Each daughter cell produced through mitosis is genetically identical to the parent cell.
• Mitosis consists of four stages: prophase, metaphase, anaphase, and telophase.
• In prophase, mitosis begins, centrioles appear and move to opposite poles of the cell, spindle fibers form between the poles, the nuclear membrane disintegrates, and chromatin starts to coil into chromosomes.
• In metaphase, chromatids line up in the equator and attach to the spindle fibers by their centromeres.
• In anaphase, chromatids separate and move to opposite poles of the cell.
• In telophase, two nuclei form, the nuclear membranes reform, chromosomes appear as chromatin again, and a cleavage furrow may form.
