  • phases of mitosis
    1. prophase
    2. metaphase
    3. anaphase
    4. telophase
  • prophase - chromatin condenses into visible chromosomes, nuclear envelope breaks down
  • metaphase - centromeres attach to spindle fibres, chromosomes line up at equator of cell
  • anaphase - sister chromatids separate from each other, pulled apart by spindle fibres towards opposite poles of the cell
  • telophase - new nuclei form around separated sets of chromosomes, cytoplasm divides by cytokinesis
  • 46 chromosomes in a human cell, 23 pairs of chromosomes
