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: -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.

Detailed explanation-3: -After gaining entry into the body, a virus makes physical contact with and crosses the plasma membrane of a target cell. Inside, it releases and replicates its genome while facilitating the manufacture of its proteins by host ribosomes. How this is carried out depends upon the type of viral nucleic acid.

Detailed explanation-4: -This is because viruses hijack the cells of the body to replicate, whereas bacteria simply multiply on their own.
