Detailed explanation-1: -This process of host cell takeover is known as “molecular hijacking.” When a virus replicates it has to build entire viral particles and it has to not only make the proteins that comprise the viral capsid (and enclose it with an envelope), but it must also replicate its genetic material.

Detailed explanation-2: -Viruses cannot reproduce on their own. Instead, viruses replicate by infecting a host cell (such as humans, other animals, plants or bacteria), hijacking the host’s biological machinery and turning the host cell into a virus-producing factory.

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 are unable to replicate on their own, and they need the intracellular environment and energy supplies to replicate. Indeed, they use the host translation machinery to synthesize their proteins, and the cell provides structures and/or host factors to achieve the synthesis of viral genomes.

Detailed explanation-5: -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.
