Cell division in Prokaryotes

In prokaryotic cell division, called binary fission, a membrane attachment mechanism is used to allocate chromosome copies to the two daughter cells.

A diagram of the attachment of bacterial chromosomes, indicating the possible role of the mesosome (an inward fold of the cell membrane) in ensuring the distribution of the "chromosomes" in a dividing cell. Upon attachment to the plasma membrane, the DNA replicates and reattaches at separate points. Continued growth of the cell gradually separtates the chromosomes.
