Mitosis

• Prophase

  Chromosomes condense, centrosomes move to opposite poles, Spindle fibres form, nuclear envelope breaks down into small vesicles, nucleolus disappears
• Metaphase

  Centrosomes reach opposite poles,

  spindle fibres extend from centrosomes

  chromosomes line up at equator

  spindle fibres attach to centromeres using kinetic chores

  each sister chromatid is attached to a spindle fibre from an opposite pole
• Anaphase

  sister chromatids separated at centromere

  spindle fibres shorten

  chromosomes pulled to opposite poles by spindle fibres
• Telophase

  chromosomes unravel

  nuclear envelopes reform around each set of chromosomes

  spindle fibres break down

  new nucleoli form within each nucleus
