Cell Division in Prokaryotic Cells

In prokaryotes the circular DNA attaches to the cell membrane and replicates.The plasmids also replicate.The cell membrane grows between the two DNA strands as the cell divides in two leaving each new cell with one of the circular strands of DNA and a number of plasmids.Binary Fission
