•Based mainly on Virion and Kingdom of host •Use Host cell type (Animal viruses, plant viruses, etc.) •Use Nucleic Acid type (ds DNA, ss DNA, ds RNA, ss RNA) •Use + or - polarity of RNA. "+" is able to serve as mRNA. "-" is the complement of +, must function as template to make a complementary strand of + RNA before any translation can occur. •Use virus coat morphology. Enveloped vs. nonenveloped viruses. Taxonomy of viruses
