WebIt focuses on how viruses replicate and then exit from host cells. The lesson also introduces the difference between DNA and RNA viruses and explains that viruses need host proteins to replicate. Furthermore, the virus may damage the host cell during replication, either directly or indirectly, as we saw with intracellular bacteria. 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 ...
