The bacteriophage lytic cycle begins when the phage attaches via a slender stalk to the host cell. Linear DNA from the viral head is injected into the host cell. The phage DNA circularizes, remaining separate from the host DNA. The phage DNA replicates, and new phage proteins are made. New phage particles are assembled. The cell lyses, releasing the phage. The bacteriophage lysogenic cycle begins the same way as the lytic cycle, with phage infecting a host cell. However, the phage DNA becomes incorporated into the host genome. The cell divides, and phage DNA is passed on to daughter cells. Under stressful conditions, the phage DNA is excised from the bacterial chromosome and enters the lytic cycle.

Steps of a viral infection, illustrated generically for a virus with a + sense RNA genome.1. Attachment. Virus binds to receptor on cell surface.2. Entry. Virus enters cell by endocytosis. In the cytoplasm, the capsid comes apart, releasing the RNA genome.3. Replication and gene expression. The RNA genome is copied (this would be done by a viral enzyme, not shown) and translated into viral proteins using a host ribosome. The viral proteins produced include capsid proteins.4. Assembly. Capsid proteins and RNA genomes come together to make new viral particles.5. Release. The cell lyses (bursts), releasing the viral particles, which can then infect other host cells.
