NEET BIOLOGY

Detailed explanation-1: -It has been known for decades that once a virus gets inside a cell, it hijacks the cellular processes to produce virally encoded protein that will replicate the virus’s genetic material.

Detailed explanation-2: -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.

Detailed explanation-3: -Viral entry is the earliest stage of infection in the viral life cycle, as the virus comes into contact with the host cell and introduces viral material into the cell.

Detailed explanation-4: -Viruses contain either RNA or DNA as their genetic material. DNA in most organisms is a double-stranded structure, based on Watson and Crick pairing; however, in viruses, DNA and RNA can be either single-stranded or double-stranded.

Detailed explanation-5: -Instead, viruses enter living cells and then hijack the host’s cellular equipment to copy viral genetic information, build new capsids, and assemble everything together. We use the term replicate, instead of reproduce, to indicate viruses need a host cell to multiply.
