A virus is a small infectious agent, that requires a living cell to replicate itself. It can infect life forms like animals, plants and microorganisms like bacteria and archaea. It consists of nucleic acid typically in the form of RNA, which is covered with protective coat of proteins also called as capsid. It derives an envelop of lipid from the cell membrane of the host cell.
