Detailed explanation-1: -During the transcription and biosynthesis stages, the virus hijacks the cell’s replication and translation mechanisms, using them to make more viruses. The virus’s nucleic acid uses the host cell’s metabolic machinery to make large amounts of viral components.
Detailed explanation-2: -During the lysogenic cycle, instead of killing the host, the phage genome integrates into the bacterial chromosome and becomes part of the host.
Detailed explanation-3: -In a lytic cycle, the virus introduces its genome into a host cell and initiates replication by hijacking the host’s cellular machinery to make new copies of the virus. Once infection is complete, the newly replicated and assembled virus particles are released through lysis of the host cell into the surrounding waters.
Detailed explanation-4: -Step 1: Adsorption. Step 2: Penetration. Step 3: Replication. Step 4: Maturation. Step 5: Release. Step 6: Reinfection. 09-Apr-2022
