Most&nbsp;viruses&nbsp;have either RNA or&nbsp;DNA&nbsp;as their genetic material. The nucleic acid may be single- or double-stranded. The entire infectious&nbsp;virus&nbsp;particle, called a virion, consists of the nucleic acid and an outer shell of protein. The simplest&nbsp;viruses&nbsp;contain only enough RNA or&nbsp;DNA&nbsp;to encode four proteins. A&nbsp;<a href="https://www.ncbi.nlm.nih.gov/books/n/mcb/A7315/#A7862">virus</a>&nbsp;is a small parasite that cannot reproduce by itself. Once it infects a susceptible cell, however, a&nbsp;<a href="https://www.ncbi.nlm.nih.gov/books/n/mcb/A7315/def-item/A7862/">virus</a>&nbsp;can direct the cell machinery to produce more viruses.
