  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. 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 ...

  5. 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]

  6. Riboviria - Wikipedia

    en.wikipedia.org/wiki/Riboviria

    Viruses that replicate via RdRp belong to three groups in the Baltimore classification system, all of which are in the kingdom Orthornavirae: single-stranded RNA (ssRNA) viruses, which are either positive (+) or negative (-) sense, and double-stranded RNA viruses (dsRNA). +ssRNA viruses have genomes that can functionally act as mRNA, and a ...

  7. Totiviridae - Wikipedia

    en.wikipedia.org/wiki/Totiviridae

    Life cycle of S. cerevisiae virus L-A. Viral replication is cytoplasmic. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. Translation takes place by -1 ribosomal frameshifting, +1 ribosomal frameshifting, viral initiation, and RNA termination-reinitiation.

  8. 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.

  9. Baltimore classification - Wikipedia

    en.wikipedia.org/wiki/Baltimore_classification

    Baltimore classification groups viruses together based on their manner of mRNA synthesis. Characteristics directly related to this include whether the genome is made of deoxyribonucleic acid (DNA) or ribonucleic acid (RNA), the strandedness of the genome, which can be either single- or double-stranded, and the sense of a single-stranded genome, which is either positive or negative.
