Cell Cycle

• What is mitosis?

  A cycle that produces two daughter nuclei with the same number of chromosomes as the parent cell and each other

  Has an exact copy of the DNA of the parent cell

  Important for growth and replacing damaged or worn-out cells
• What is interphase?

  Comes before mitosis

  During this, the DNA is replicated so there is now two identical copies of each chromosome
• What are the stages of mitosis in order?


  (Interphase), Prophase, Metaphase, Anaphase, Telophase
• What is prophase?

  Chromosomes become visible, and are seen as two chromatids joined together

  Nuclear envelope disappears
• What is metaphase?

  Chromosomes arrange themselves at the centre of the cell (equator)
• What is anaphase?

  Chromatids of each pair of chromosomes migrate to opposite poles of the cell
• What is telophase?

  New chromosomes collect at the opposite poles of the cell

  Nuclear envelope reforms around each set, producing two daughter nuclei
