Binary fission is the most common mode of reproduction in bacteria. It is an asexual type of reproduction in which the bacterial cell divides into two daughter cells of equal size. The DNA molecule replicates, resulting in the formation of two chromosomes. The chromosomes are attached to the plasma membrane through the mesosome. The chromosome divides along with the mesosome. The two daughter mesosomes formed migrate to the opposite sides through the attachment to the plasma membrane and carry the chromosomes along with them. The cytoplasmic membrane invaginates and the cell wall is laid between the two chromosomes. Finally, the two bacterial cells separate.
