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.
Sedoreoviridae (formerly Reoviridae) is a family of double-stranded RNA viruses. Member viruses have a wide host range, including vertebrates , invertebrates , plants, protists and fungi. [ 1 ] They lack lipid envelopes and package their segmented genome within multi-layered capsids .
Dinovernavirus is a genus of double-stranded RNA viruses in the family Reoviridae and subfamily Spinareovirinae.Member viruses replicate in a variety of mosquito cell lines. . The name is an abbreviation for double-stranded, insect, novem (Latin for nine the number of genome segments), rna vir
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. [2] They form the genetic material of some viruses (double-stranded RNA viruses). dsRNA, such as viral RNA or siRNA, can trigger RNA interference in eukaryotes, as well as ...

The structure of adenovirus. 1 = penton capsomers, 2 = hexon capsomers, and 3= viral genome (linear dsDNA) Adenoviruses are medium-sized (90–100 nm). [ 2 ] The virions are composed of one linear piece of double-stranded DNA inside an icosahedral capsid . 240 hexon proteins make up the bulk of the capsid, while twelve penton bases cap the ...
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 ...
