Viruses are strange life forms.
The word virus is more correctly applied to a species or genus of virus rather than to the individual particles. The nucleic acids within the viral particles are surrounded by a protein coat, and sometimes an additional fatty envelope. The capsid consists of this protein coat and any fatty layer. The capsid proteins are crucial to the virus' ability to attach and infect a host cell. It enables the cell to live and function within a body.
