Double-stranded RNA viruses (dsRNA viruses) are a polyphyletic group of viruses that have double-stranded genomes made of ribonucleic acid.The double-stranded genome is used as a template by the viral RNA-dependent RNA polymerase (RdRp) to transcribe a positive-strand RNA functioning as messenger RNA (mRNA) for the host cell's ribosomes, which translate it into viral proteins.
Double-stranded RNA (dsRNA) is RNA with two complementary strands found in cells. It is similar to DNA but with the replacement of thymine by uracil and the adding of one oxygen atom. [ 1 ] Despite the structural similarities, much less is known about dsRNA.
Viruses in the family Reoviridae have genomes consisting of segmented, double-stranded RNA (dsRNA). [4] Because of this, replication occurs exclusively in the cytoplasm, and the virus encodes several proteins which are needed for replication and conversion of the dsRNA genome into positive-sense RNAs. [10]

Taxonomy and replication strategies of different types of RNA viruses. An RNA virus is a virus characterized by a ribonucleic acid based genome. [1] The genome can be single-stranded RNA or double-stranded (dsRNA). [2]

Genome type and replication cycle of different RNA viruses. RNA viruses in Orthornavirae typically do not encode many proteins, but most positive-sense, single-stranded (+ssRNA) viruses and some double-stranded RNA (dsRNA) viruses encode a major capsid protein that has a single jelly roll fold, so named because the folded structure of the protein contains a structure that resembles a jelly ...
