An RNA virus is a virus that either uses RNA as its genetic material, or whose genetic material passes through an RNA intermediate during replication. For example, Hepatitis B virus is classified as an RNA virus, even though its genome is double-stranded DNA, because the genome is transcribed into RNA during replication. The basis for this classification is error-prone RNA replication: All RNA viruses have very high mutation rates because they lack DNA polymerases which can find and edit out mistakes. DNA viruses have considerably lower mutation rates. See also retroviruses.
