Final answer:
The five steps of viral replication for a virulent bacteriophage in the lytic cycle are attachment, penetration, biosynthesis, maturation, and release, resulting in the destruction of the host cell and the spread of new virions.
Step-by-step explanation:
The five steps of viral replication for a virulent bacteriophage, which exhibits only the lytic cycle, can be summarized as follows:
-
-
-
-
-
This cycle can lead to the production of new virions that continue to infect other bacterial cells. In contrast, some viruses can enter a lysogenic cycle or a state of latency, where they integrate into the host genome and replicate along with the cell without causing immediate lysis.
