Now, let's move on to the second type of asexual reproduction known as binary fission. So binary fission is the asexual reproduction that bacterial cells as well as other prokaryotic cells actually undergo. So what happens is inside the bacterial cell we have circular DNA, and the circular DNA basically begins to replicate itself. As that takes place, the original DNA shown in blue and the replicated DNA shown in green attached to different positions on the cell membrane. At the same time, the cell begins to expand and the cell begins to grow. Eventually, once we replicate our DNA, the cell basically divides into equal size daughter cells as shown in the following diagram.
