NEET BIOLOGY

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: -Endocytosis: The host cell takes in the viral particle through the process of endocytosis, essentially engulfing the virus like it would a food particle. Viral penetration: The viral capsid or genome is injected into the host cell’s cytoplasm.

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.
