Binary fission is a method of asexual reproduction that takes place in the prokaryotic cells. Binary fission gives rise to two new daughter cells that carry the genetic material the same as that of the parental cell. The bacterial cells lack a defined nucleus and they have a single, circular-shaped chromosome. This chromosome gets replicated by the action of certain enzymes.
Meanwhile, the cell increases in size and the newly formed chromosomes move to the opposite ends. The cell membrane pinches inwards and the cytoplasm divides into two parts and hence gives rise to two individual bacterial cells.
