Detailed explanation-1: -Viruses cannot replicate on their own, but rather depend on their host cell’s protein synthesis pathways to reproduce. This typically occurs by the virus inserting its genetic material in host cells, co-opting the proteins to create viral replicates, until the cell bursts from the high volume of new viral particles.
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: -All living organisms have double-stranded DNA genomes. Viruses with dsDNA genomes therefore have the most similar nucleic acid to living organisms and often use the enzymes and proteins that the cell normally uses for DNA replication and transcription, including its DNA polymerases and RNA polymerases.
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. Next, the viral particles are assembled into new viruses.
