Inside the organism, the virus can enter a cell in various ways. bacteriophages —bacterial viruses—attach to the cell wall surface in specific ... cell at these exit sites, referred to as exocytosis. On the other hand, bacteriophages must break open, or lyse , the cell to exit. To do this, the phages have ...

Immune system

... to the blood. Bacteria and monocellular organisms have an "immune system" (under the broader of the two definitions above) designed to combat bacteriophages (viruses that infect bacteria). They do this by simultaneously expressing restriction enzymes that cut DNA at certain sequences, and enzymes ...
