Detailed explanation-1: -Viruses are fully reliant on the translation machinery of their host cells to produce the polypeptides that are essential for viral replication.

Detailed explanation-2: -Viruses are obligate intracellular parasites. They enter host cells, they use host cell machineries to replicate their genome and synthesize their proteins, and they produce progeny virions that are released in the extracellular environment.

Detailed explanation-3: -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-4: -Viruses clearly rely on host cell machinery to propagate-they promote anabolism for generation of macromolecules needed for virion replication and assembly. Therefore, it is not surprising that viral infection triggers metabolic reprogramming in host cells to facilitate optimal virus production.
