WebBaltimore classification (first defined in 1971) is a classification system which places viruses into one of seven groups depending on a combination of their nucleic acid ( DNA or RNA ), strandedness (single-stranded or double-stranded), and method of replication. Baltimore classification is a system used to classify viruses based on their manner of messenger RNA (mRNA) synthesis. By organizing viruses based on their manner of mRNA production, it is possible to study viruses that behave similarly as a distinct group. Seven Baltimore groups are described that take into consideration whether the viral genome is made of deoxyribonucleic acid (…

Rather than assigning viruses to taxa, Baltimore grouped all viruses into six disconnected groups without any subdivisions, now commonly referred to as Baltimore Classes (BCs).

WebGroup VI viruses have diploid (two copies) ssRNA genomes that must be converted, using the enzyme reverse transcriptase, to dsDNA; the dsDNA is then transported to the nucleus of the host cell and inserted into the host genome. Then, mRNA can be produced by transcription of the viral DNA that was integrated into the host genome.
