The cell cycle

• What are the 4 stages of the cell cycle?

  • Interphase (G1, S G2)
  • Mitosis (M)
  • G1, cell growth
  • S, DNA Synthesises
  • G2, growth and preparation for Mitosis
  • M, Mitosis or meiosis
• What is the calculation for mitotic index?

  • Number of cells in Mitosis ÷ total number of cells x100
• How do bacteria replicate?

  • Binary fission
• What happens in binary fission?

  • Circular DNA and plasmids are replicated
  • Division of cytoplasm to produce 2 genetically identical cells
