Viruses are not cells and cannot divide. They infect a host cell and use the host’s replication processes to produce identical progeny virus particles. Viruses infect organisms as diverse as bacteria, plants, and animals and exist in a netherworld between a living organism and a nonliving entity. Living things grow, metabolize, and reproduce.

Some large viruses have been found. Virions are acellular and consist of a nucleic acid, DNA or RNA, but not both, surrounded by a protein capsid. There may also be a phospholipid membrane surrounding the capsid. Viruses are obligate intracellular parasites.

It cannot self-replicate and is completely reliant on the cellular biochemistry of whatever host cell it has infected. The minimal definition of a virus is a nucleic acid genome inside of a protein shell, or capsid. There are variations of this, such as virions that have a membrane coat outside of the capsid, or some that have enzymes inside of the capsid alongside the genome.
