Detailed explanation-1: -HBV Genome Replication. HBV DNA replication takes place in the cytoplasm, the venue for viral protein synthesis (Fig.
Detailed explanation-2: -Initiation of viral protein synthesis takes place in the 5′ NTR, which houses the internal ribosome entry site (IRES). Following translation of mRNA, the viral proteins are originated by proteolytic cleavage.
Detailed explanation-3: -As viruses have no ribosomes, mitochondria, or other organelles, they are completely dependent on their cellular hosts for energy production and protein synthesis. They replicate only within cells of the host that they infect.
Detailed explanation-4: -The virus’s genome is uncoated from the protein and injected into the host cell. Then the viral genome hijacks the host cell’s machinery, forcing it to replicate the viral genome and produce viral proteins to make new capsids.
