Virus VIRUSES A Virus is a small particle that contains proteins and heredity material (DNA or RNA), but is not alive. The virus is surrounded by a protein coat, or capsid A virus particle can not eat, metabolize food and can only reproduce inside a cell. Outside the cell, the virus particle does nothing and remains inactive. Viruses are cell specific meaning they can only infect a cell if the capsid of the virus can fit into a receptor site in the host cell membrane. You can think of it as
