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

6
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?)

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.
