Detailed explanation-1: -Viral capsid proteins protect the fragile genome, composed of nucleic acid, from the harsh environment. The capsid and nucleic acid together are known as the nucleocapsid.

Detailed explanation-2: -When a virus particle is independent from its host, it consists of a viral genome, or genetic material, contained within a protein shell called a capsid.

Detailed explanation-3: -Virus particles contain the viral genome packaged in a protein coat called the capsid. For some viruses, the capsid is surrounded by lipid bilayer that contains viral proteins, usually including the proteins that enable the virus to bind to the host cells.
