Bacterial Division

  • Bacteria multiply by simple cell division
  • One bacterial cell splits onto two this is called binary fission
  • Bacteria can doo this about once every 20 minutes as long as they have enough nutrients and the temperature is suitable

Mitosis

The Process:

  • First the DNA replicates to form 2 copies of each chromosome and the cell grows and copies internal structures
  • Then the nuclear membrane breaks down and the chromosomes line up across the centre of the cell
  • One set of chromosomes is pulled to each end and split
  • The cytoplasm and cell membranes divide to form 2 identical daughter cells
