Explanation:
Usually a virus is mainly made up of genetic material (DNA or RNA) inside a capsid/envelope. It has no organelles like a ‘true’ cell. Because it cannot reproduce on its own, scientists struggle to categorize it as a living thing since reproduction is a property of living things. The virus reproduces by hijacking the cellular mechanisms of the host cells to replicate itself. It does so by integrating itself in the genome of the host so that its DNA is also replicated, along with that of the host, by the host cell DNA polymerases and its proteins produced by the ribosomes of the host.
