Genome type and replication cycle of different RNA viruses. RNA viruses in Orthornavirae typically do not encode many proteins, but most positive-sense, single-stranded (+ssRNA) viruses and some double-stranded RNA (dsRNA) viruses encode a major capsid protein that has a single jelly roll fold, so named because the folded structure of the protein contains a structure that resembles a jelly ...
This is the single largest group of RNA viruses [23] and has been organized by the ICTV into the phyla Kitrinoviricota, Lenarviricota, and Pisuviricota in the kingdom Orthornavirae and realm Riboviria. [24] Positive-strand RNA viruses can also be classified based on the RNA-dependent RNA polymerase. Three groups have been recognised: [25]
Small RNA that is activated by SgrR in Escherichia coli during glucose-phosphate stress shRNA: short hairpin RNA - siRNA: small interfering RNA - SL RNA spliced leader RNA multiple families: SmY RNA: mRNA trans-splicing RF01844: Small nuclear RNAs found in some species of nematode worms, thought to be involved in mRNA trans-splicing snoRNA ...
Group VI: viruses possess single-stranded RNA viruses that replicate through a DNA intermediate. The retroviruses are included in this group, of which HIV is a member. Group VII : viruses possess double-stranded DNA genomes and replicate using reverse transcriptase.

Virus classification showing major ranks This is a list of genera of biological viruses. See also Comparison of computer viruses. This is an alphabetical list of genera of biological viruses. It includes all genera and subgenera of viruses listed by the International Committee on Taxonomy of Viruses (ICTV) 2022 release. [1]
This is a list of all virus species, including satellites and viroids. Excluded are other ranks, and other non-cellular life such as prions. Also excluded are common names and obsolete names for viruses. The taxonomy is taken from ICTV taxonomy 2022 release [1] For a list of virus families and subfamilies, see List of virus families and ...
Kitrinoviricota is a phylum of RNA viruses that includes all positive-strand RNA viruses that infect eukaryotes and are not members of the phylum Pisuviricota or Lenarviricota. [1] The name of the group derives from Greek κίτρινος ( kítrinos ), which means yellow (a reference to yellow fever virus ), and - viricota , which is the ...
