ribonucleic acid(ˌraɪbəʊnjuːˈkliːɪk; -ˈkleɪ-)
(Biochemistry) the full name of RNA
[C20: from ribo(se) + nucleic acid]
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.
1. (RNA) A molecule that transfers information essential for protein synthesis from DNA.
2. (RNA) Nucleic acids that help to produce proteins in living cells.

|Noun||1.||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
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
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)
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
