  2. Double-stranded RNA viruses - Wikipedia

    en.wikipedia.org/wiki/Double-stranded_RNA_viruses

    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.

  3. Viral replication - Wikipedia

    en.wikipedia.org/wiki/Viral_replication

    RNA viruses lack the capacity to identify and repair mismatched or damaged nucleotides, and thus, RNA genomes are prone to mutations introduced by mechanisms intrinsic and extrinsic to viral replication. [18] RNA viruses present a therapeutic double-edged sword: RNA viruses can withstand the challenge of antiviral drugs, cause epidemics, and ...

  4. RNA virus - Wikipedia

    en.wikipedia.org/wiki/RNA_virus

    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]

  5. Orthornavirae - Wikipedia

    en.wikipedia.org/wiki/Orthornavirae

    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 ...

  6. Double-stranded RNA - Wikipedia

    en.wikipedia.org/wiki/Double-stranded_RNA

    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.

  7. Sedoreoviridae - Wikipedia

    en.wikipedia.org/wiki/Sedoreoviridae

    Life cycle of a reovirus. 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]

  8. Alphachrysovirus - Wikipedia

    en.wikipedia.org/wiki/Alphachrysovirus

    Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. The virus exits the host cell by cell to cell movement. Fungi serve as the natural host. [1] [3]

  9. Rotavirus - Wikipedia

    en.wikipedia.org/wiki/Rotavirus

    The eleven dsRNA strands remain within the protection of the two protein shells and the viral RNA-dependent RNA polymerase creates mRNA transcripts of the double-stranded viral genome. By remaining in the core, the viral RNA evades innate host immune responses including RNA interference that are triggered by the presence of double-stranded RNA ...
