Binary Fission

  • Bacteria multiply by a type of simple cell division known as binary fission
  • In the right conditions, a bacterial cell prepares to divide by replicating its genetic material before it increases in size. A copy of each piece of circular DNA moves to each end of the cell before the cytoplasm divides, and new cell walls form around each daughter cell
