So a cell whose genome contains a viral DNA section inside that cell is known as a provirus. So these are the two types of cycles of pathways that can be followed by our cell once the virus actually ingests itself or injects the nucleic acid into that whole cell. A specific type of virus that only infects and targets bacterial cells is known as the bacteria phase and this usually undergoes the Litig cycle. There are also different types of viruses. For example, the HIV virus, virus that doesn't only undergo the Litig cycle, it can also undergo the lysogenic cycle. In the lipogenic cycle the DNA of that virus is actually incorporated, it's integrated with the DNA of that whole cell.
