Virus, infectious agent of small size and simple composition that can multiply only in living cells of animals, plants, or bacteria Viruses possess unique infective properties and thus often cause disease in host organisms Learn about the history, types, and features of viruses

A virus is a small piece of genetic information in a “carrying case” — a protective coating called a capsid Viruses aren’t made up of cells, so they don’t have all the equipment that cells do to make more copies of themselves

A virus is an infectious microbe consisting of a segment of nucleic acid (either DNA or RNA) surrounded by a protein coat A virus cannot replicate alone; instead, it must infect cells and use components of the host cell to make copies of itself

A virus is a chain of nucleic acids (DNA or RNA) which lives in a host cell, uses parts of the cellular machinery to reproduce, and releases the replicated nucleic acid chains to infect more cells

In a nutshell, a virus is a non-cellular, infectious entity made up of genetic material and protein that can invade and reproduce only within the living cells of bacteria, plants and animals For instance, a virus cannot replicate itself outside the host cell This is because viruses lack the required cellular machinery
