Baltimore classification groups viruses together based on their manner of mRNA synthesis. Characteristics directly related to this include whether the genome is made of deoxyribonucleic acid (DNA) or ribonucleic acid (RNA), the strandedness of the genome, which can be either single- or double-stranded, and the sense of a single-stranded genome, which is either positive or negative.
Virus classification is the process of naming viruses and placing them into a taxonomic system similar to the classification systems used for cellular organisms. Viruses are classified by phenotypic characteristics, such as morphology , nucleic acid type, mode of replication, host organisms , and the type of disease they cause.
The older Baltimore classification (pictured), proposed in 1971 by David Baltimore, places viruses into seven groups (I–VII) based on their nucleic acid type, number of strands and sense, as well as the method the virus uses to generate mRNA. There is some concordance between Baltimore groups and the higher levels of the ICTV scheme.
The kingdom contains three groups in the Baltimore classification system, which groups viruses together based on their manner of mRNA synthesis, and which is often used alongside standard virus taxonomy, which is based on evolutionary history. Those three groups are Group III: dsRNA viruses, Group IV: +ssRNA viruses, and Group V: -ssRNA viruses.
David Baltimore, a Nobel Prize-winning biologist, devised a system called the Baltimore Classification System to classify different viruses based on their unique replication strategy. There are seven different replication strategies based on this system (Baltimore Class I, II, III, IV, V, VI, VII).
The Baltimore Classification of viruses is based on the method of viral mRNA synthesis. The Nobel Prize-winning biologist David Baltimore devised the Baltimore classification system. [102] [103] The ICTV classification system is used in conjunction with the Baltimore classification system in modern virus classification. [104] [105] [106]

Riboviria partially merges Baltimore classification with virus taxonomy, including the Baltimore groups for RNA viruses and reverse transcribing viruses in the realm. Baltimore classification is a classification system used for viruses based on their manner of mRNA production, often used alongside standard virus taxonomy, which is based on ...
