WebBacteria can replicate approximately every 20 minutes by binary fission, which is a simple form of cell division. This level of replication will depend on the availability of nutrients … WebApr 8, 2016 · Bacteria reproduce by a process called binary fission. In binary fission (shown in Figure 2), the bacterium first duplicates its DNA, so it has two identical copies of genetic material. The cell then swells and elongates as it gets ready to split, with the copies of DNA moving to separate sides of the cell. A divider then forms in the middle of ...
