The smallest RNA virus in terms of genome size is phage BZ13 strain T72 at 3,393 nucleotides length. [14] Viruses using both DNA and RNA in their replication ( retroviruses ) range in size from 7,040 to 12,195 nucleotides. [ 15 ]
The average virus is about 1/100 the size of the average bacterium, and most are too small to be seen directly with an optical microscope. The origins of viruses are unclear: some may have evolved from plasmids, others from bacteria. Viruses are sometimes considered to be a life form, because they carry genetic material, reproduce and evolve ...

A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. [1] Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. [2] [3] Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity.
A giant virus, sometimes referred to as a girus, is a very large virus, some of which are larger than typical bacteria. [ 1 ] [ 2 ] All known giant viruses belong to the phylum Nucleocytoviricota . [ 3 ]
50 nm – upper size for airborne virus particles; 50 nm – flying height of the head of a hard disk [77] 65 nm – the average half-pitch of a memory cell manufactured circa 2005–2006; 58 nm – height of a T7 bacteriophage; 90 nm – human immunodeficiency virus (HIV) (generally, viruses range in size from 20 nm to 450 nm)
