Viruses in the family Guttaviridae are enveloped. The diameter is around 55âÂÂ80 nm, with a length of 75âÂÂ130 nm. Genomes are circular double-stranded DNA around 14 kilobases in length. Virions are ovoid or droplet-shaped and covered with globular subunits.
DNA-templated transcription is the method of transcription. Archaea serve as the natural host.
