Binary Fission

• In which type of cell does binary fission occur?

  Prokaryotic cells
• How does binary fission work?

  • The strands of DNA and plasmids replicate
  • Cell gets bigger and DNA moves to opposite sides
  • Cytoplasm begins to divide and new cell walls form
  • Cytoplasm divides and two daughter cells are produced
• How much DNA do daughter cells contain after binary fission?

  Each has one strand of DNA but a variable number of plasmids
• How often can bacteria reproduce in favourable conditions?

  Every 20 minutes
