  2. Double-stranded RNA - Wikipedia

    en.wikipedia.org/wiki/Double-stranded_RNA

    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 ...

  3. Nucleic acid test - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_test

    Nucleic acid (DNA and RNA) strands with corresponding sequences stick together in pairwise chains, zipping up like Velcro tumbled in a clothes dryer. But each node of the chain is not very sticky, so the double-stranded chain is continuously coming partway unzipped and re-zipping itself under the influence of ambient vibrations (referred to as thermal noise or Brownian motion).

  4. Anti-dsDNA antibodies - Wikipedia

    en.wikipedia.org/wiki/Anti-dsDNA_antibodies

    Anti-double stranded DNA (Anti-dsDNA) antibodies are a group of anti-nuclear antibodies (ANA) the target antigen of which is double stranded DNA. Blood tests such as enzyme-linked immunosorbent assay (ELISA) and immunofluorescence are routinely performed to detect anti-dsDNA antibodies in diagnostic laboratories.

  5. 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.

  6. RNA - Wikipedia

    en.wikipedia.org/wiki/RNA

    Unlike double-stranded DNA, RNA is usually a single-stranded molecule (ssRNA) [4] in many of its biological roles and consists of much shorter chains of nucleotides. [5] However, double-stranded RNA (dsRNA) can form and (moreover) a single RNA molecule can, by complementary base pairing, form intrastrand double helixes, as in tRNA.

  8. Nucleic acid hybridization - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_hybridization

    In molecular biology, hybridization (or hybridisation) is a phenomenon in which single-stranded deoxyribonucleic acid or ribonucleic acid molecules anneal to complementary DNA or RNA. [1] Though a double-stranded DNA sequence is generally stable under physiological conditions, changing these conditions in the laboratory (generally by raising ...

  9. RNA-dependent RNA polymerase - Wikipedia

    en.wikipedia.org/wiki/RNA-dependent_RNA_polymerase

    Viruses containing positive-strand RNA or double-strand RNA, except retroviruses and Birnaviridae. All positive-strand RNA eukaryotic viruses with no DNA stage, such as Coronaviridae; All RNA-containing bacteriophages; the two families of RNA-containing bacteriophages are Fiersviridae (positive ssRNA phages) and Cystoviridae (dsRNA phages)
