  1. Cell Cycle: Mitosis

  2. Cytokinesis is the division of the cell into two Mitosis is the division of the nucleus into two

  3. (a) Interphase (b) Late prophase (c) Metaphase (f) interphase (e) Telophase (d) Anaphase

  4. Stages of Mitosis (PMAT) • Prophase • Chromosomes become distinct • Centrosome divides and migrates to opposite ends of the cell • Nuclear envelope breaks down • Metaphase • Chromosomes line up on the cell metaphase plate • Anaphase • Telophase

  5. Stages of Mitosis (PMAT) • Prophase • Metaphase • Anaphase • Chromosomes crawl along the microtubules of the mitotic spindle • Telophase • Chromosomes become less distinct • Nucleolus and nuclear envelope reappear (are formed?)

  6. Apoptosis - When cells commit suicide • One of the ways the body prevents cancer is to send a signal for cancerous cells to commit suicide • This signal can be stimulated by a protein called p53. Cancer nearly always involves loss of function of p53.
