Bacteria and other prokaryotic cells replicate by a process known as binary fission. Cells that undergo binary fission make copies of their genetic material, then split into two daughter cells.

The process of binary fission

(2) - The circular DNA and plasmid(s) replicate.

(3) - The cell gets bigger, and the circular DNA strands move to opposite 'poles' (ends) of the cell.

(4) - A daughter cell is produced after the cytoplasm divides. Each daughter cell has one copy of the circular DNA but may have a variable number of copies of the plasmid(s).
