Classification of viruses MDCAT Quiz: The Classification of Viruses is the system scientists use to classify the viruses according to their characteristics: structure, genetic material, replication method, and the host organisms. Viruses in themselves are special because they don’t have all the hallmarks of life, and when they infect host cells, they replicate. The ICTV is an organization responsible for the classification of viruses into families, genera, and species. Primary criteria include type of genetic material (DNA or RNA), capsid shape, and replication. Viruses are classically divided mainly into two categories: DNA viruses and RNA viruses, and further sub-classified as follows. All MDCAT students need to learn how viruses are classified to face questions from microbiology and virology and the diseases caused by these viruses.
