mitosis

• prophase


  • chromosome condense. now visible
  • centriole move to opposite poles
  • spinde fibres form
  • nucleolus break down
• metaphase


  • chromosome line up at equator
  • spindle fibres attach to centromeres
• anaphase


  • centromeres divide
  • spindle fibre contract (seperates sister chromatids)
  • chromatids move to opposite poles
  • spindle fibre break down
• telophase


  • 2 nuclear envelope form around each chromosome
  • chromosome unravel
  • forming chromatin
• what are uses for mitosis?


  • growth
  • repair
  • asexual reproduction
• interphase


  • consists of G1, S, G2
  • G1 = cell size doubles, produces proteins for replication
  • S = DNA replication
  • G2 = organelles divide
• cytokinesis


  • cell membrane pinches centre of cell
  • separates cells into 2
  • cytoplasm divides
