ribonucleic acid, RNA - (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"

To do so they analyzed the upper part of the tRNA molecule, known as the acceptor stem, where partner synthetases bind.
tRNA consists of two coaxially stacked helices which appear to be independent structural and functional domains: the top half contains the acceptor stem and the T[Psi]C stemloop, and the bottom half contains the D stem-loop and the anticodon stem-loop [ILLUSTRATION FOR FIGURE 1 OMITTED].
