Detailed explanation-1: -The lytic cycle, which is also commonly referred to as the “reproductive cycle” of the bacteriophage, is a six-stage cycle. The six stages are: attachment, penetration, transcription, biosynthesis, maturation, and lysis.

Detailed explanation-2: -The lytic cycle involves four steps: infecting a host (an action called exposure), injecting a cell with the virus’s genetic material, using the cell’s metabolic engines to create new viruses, and finally, weakening the cell walls until the host cell lyses, or bursts open from excessive internal pressure.

Detailed explanation-3: -Viral replication involves six steps: attachment, penetration, uncoating, replication, assembly, and release. During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it.

Detailed explanation-4: -Step 1: Adsorption. Attachment sites on the bacteriophage adsorb to receptor sites on the host bacterium (see Figure 10.7A. Step 2: Penetration. Step 3: Replication. Step 4: Maturation. Step 5: Release. 09-Apr-2022

Detailed explanation-5: -1-attachment. attach to the cell. 2-penetration. only nucleic acid is injected into the cell through the hole caused by the tail fibers and enzymes. 3-synthesis. replication of viral nucleic acid and protein and envelope. 4-assembly. 5-release.
