mitosis

• forms 2 genetically identical daughter cells
• daughter cells are diploid
• there is no crossing over or no homologous pairs
• interphase (not part of mitosis)


  chromosomes extend and replicate (not visible)

  centrioles are replicated

  nucleus is visible

  nuclear envelope is present
• prophase

  chromosomes condense and become visible

  nucleus disappears

  nuclear envelope breaks down

  spindle apparatus composed of spindle fibres form

  centrioles move to opposite poles
• metaphase

  nuclear membrane completely breaks down

  chromosomes align in the equator of the cell

  each chromosome is attached to a spindle fibre by its centriole
• anaphase

  centromere of each chromosome splits

  chromatids are formed

  move to centrioles at the poles of the cell

  chromatids are now separated
• telophase

  nuclear membrane reforms around each of newly divided chromosomes

  nucleolus reforms

  spindle fibres disappear

  chromosomes extend and become invisible
• cytokinesis 


  division of all the other material in the cell

  results in formation of 2 new daughter cells
