Question

Explain why a virus, a viroid, and a prion are non lving things.

Answer 1

Answer:

Viruses, prions and viroids are non-living organisms that require a living cellular host in order to reproduce. They cannot do it on their own. These parasites may be just a string of RNA, as in a viroid, or a length of DNA enclosed in a protein shell, as in a virus.
