The doublestranded (ds)RNA viruses represent a diverse group of viruses that vary widely in host range (humans, animals, plants, fungi, and bacteria), genome segment number (one to twelve), and virion organization (Tnumber, capsid layers, or turrets) Members of this fascinating group include the rotaviruses, renowned globally as the commonest cause of gastroenteritis in · A shared feature of all segmented RNA viruses is their capacity to exchange genome segments during coinfection by a process called reassortment Specifically, when two or more viruses infect aImportant functional similarities include (1) the presence of a capsidbound RNAdependent RNA polymerase, which produces singlestranded mRNA transcripts from the dsRNA genome and regenerates the dsRNA genome from singlestranded RNA templates;
All doublestranded DNA viruses consist of a single large molecule, whereas most doublestranded RNA viruses have segmented genomes, with each segment usually representing a single gene that encodes the information for synthesizing a single protein Viruses with singlestranded genomic DNA are usually small, with limited genetic information(2) in viruses infecting eukaryotic hosts, the presence of all the enzymatic activities needed to generate the 5' cap32 (2)593–605 PMC free article
