Viruses

Viruses. Ooo la la. Viral Infection. Once inside the cell, 2 different processes can occur – lytic or lysogenic. Lytic Infection. A virus enters the cell, makes copies of itself and causes the cell to burst. For example:. Bacteriophage T4 injects its own DNA directly into the cell.

Virus = virion

Virus = virion

1. Living characteristics of viruses: They reproduce at a fantastic rate, but only in living host cells. They can mutate. 2. Nonliving characteristics of viruses They are acellular , that is, they contain no cytoplasm or cellular organelles.
