Best Answer: A complete virus particle, known as a virion, consists of nucleic acid surrounded by a protective coat of protein called a capsid.These are formed from identical protein subunits called capsomers.[53] Viruses can have a lipid envelope derived from the host cell membrane.The capsid is made from proteins encoded by the viral genome and its shape serves as the basis for morphological distinction.est Answer: A complete virus particle, known as a virion, consists of nucleic acid surrounded by a protective coat of protein called a capsid.
