A whole virus particle, often called a virion, consists of nucleic acid surrounded by a protecting coat of protein known as a capsid. These are generally formed from protein subunits referred to as capsomeres.[50] Viruses might have a lipid "envelope" derived from the host mobile membrane. The capsid is made out of proteins encoded from the viral genome and its condition serves as The idea for morphological distinction.[fifty one][fifty two] Virally-coded protein subunits will self-assemble to kind a capsid, normally demanding the presence of your virus genome.
