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)
