transfer RNA

n. Abbr. tRNA
Any of a class of RNA molecules that transport amino acids to ribosomes for incorporation into a polypeptide undergoing synthesis.

transfer RNA

n
(Biochemistry) biochem any of several soluble forms of RNA of low molecular weight, each of which transports a specific amino acid to a ribosome during protein synthesis. Sometimes shortened to: t-RNA Also called: soluble RNA See also messenger RNA, genetic code

transfer RNA



n.
any of a class of small, cloverleaf forms of RNA that transfer unattached amino acids in the cell cytoplasm to the ribosomes for protein synthesis.
Abbr.: tRNA

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"

OK, but we also know that translation requires not only the ribozyme, but also the set of encoded protein enzymes that each properly load the appropriate transfer RNA with the "right" amino acid to that tRNA such that via its anticodon site it then binds to the "right" nucleotide triplet codon for the "right" amino acid for that position in the forming protein.
