RNA

ribonucleic acid: any of a class of single-stranded nucleic acid molecules of ribose and uracil, found chiefly in the cytoplasm of cells and in certain viruses; important in protein synthesis and in the transmission of genetic information transcribed from DNA. Compare messenger RNA, ribosomal RNA, transfer RNA.

ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.ribonucleic acid - (biochemistry) a long linear polymer of nucleotides found in the nucleus but mainly in the cytoplasm of a cell where it is associated with microsomes; it transmits genetic information from DNA to the cytoplasm and controls certain chemical processes in the cell; "ribonucleic acid is the genetic material of some viruses"
biochemistry - the organic chemistry of compounds and processes occurring in organisms; the effort to understand biology within the context of chemistry
ribose - a pentose sugar important as a component of ribonucleic acid
adenine, A - (biochemistry) purine base found in DNA and RNA; pairs with thymine in DNA and with uracil in RNA
cytosine, C - a base found in DNA and RNA and derived from pyrimidine; pairs with guanine
informational RNA, messenger RNA, mRNA, template RNA - the template for protein synthesis; the form of RNA that carries information from DNA in the nucleus to the ribosome sites of protein synthesis in the cell
nRNA, nuclear RNA - ribonucleic acid found in the nucleolus of the cell
acceptor RNA, soluble RNA, transfer RNA, tRNA - RNA molecules present in the cell (in at least 20 varieties, each variety capable of combining with a specific amino acid) that attach the correct amino acid to the protein chain that is being synthesized at the ribosome of the cell (according to directions coded in the mRNA)
guanine, G - a purine base found in DNA and RNA; pairs with cytosine
nucleic acid - (biochemistry) any of various macromolecules composed of nucleotide chains that are vital constituents of all living cells
polymer - a naturally occurring or synthetic compound consisting of large molecules made up of a linked series of repeated simple monomers
U, uracil - a base containing nitrogen that is found in RNA (but not in DNA) and derived from pyrimidine; pairs with adenine

Austin, TX, October 03, 2015 --(PR.com)-- Ribonucleic Acid or RNA is a molecule critical to biology because it is behind the coding, regulation and expression of genes.
The complex feline coronavirus is particularly challenging, he says, explaining that RNA viruses, those with ribonucleic acid as their genetic material such as influenza and measles, "always have a narrow window on how they adapt to the environment or an animal, but the coronavirus has a much more open window to move into different territories --different species and different tissues."
A RNA virus is one that has ribonucleic acid (RNA) as its genetic material.
Researchers at Duke Health recently discovered through genetic tests on ribonucleic acid (RNA) that 60 genes are responsible for individual response to aspirin--a concept they call an "aspirin response signature." Using this information as a biomarker, the researchers were able to determine, with a simple blood test, how much aspirin a person needs to "thin" their blood--or even if aspirin will work at all.
