Summary
Viruses are non-cellular living entities. Their particles are formed by a nucleic acid surrounded by a protein capsid, which together form the so-called nucleocapsid. Nucleocapsids of some virus species are additionally enveloped by a host-cell-derived lipid envelope containing viral proteins. All three structural components (nucleic acid, capsid and envelope) are incredibly variable; for example, the viral genome can be encoded by either an RNA or DNA molecule, which can be single or double stranded, linear or circular, unsegmented or segmented, etc.
