Best Answer: The proteins that make up the virus particle are called STRUCTURAL PROTEINS. The protein coat of the virus is called the CAPSID and is made up of numerous CAPSOMERES.The combination of the viral nucleic acid and the protective protein is called the NUCLEOCAPSID. Some viruses are encased in a protective membrane called the ENVELOPE.The whole virus particle (all the parts) is called the VIRION.he combination of the viral nucleic acid and the protective protein is called the NUCLEOCAPSID.
