A Transfer RNA (abbreviated tRNA and archaically referred to as sRNA abbreviating soluble RNA) is an adaptor molecule composed of RNA, typically 73 to 94 nucleotides in length, that serves as the physical link between the nucleotide sequence of nucleic acids (DNA and RNA) and the amino acid sequence of proteins. It does this by carrying an amino a...

(tRNA) a type of RNA that brings about the transfer of specific amino acid molecules to growing polypeptide chains during the synthesis of proteins. Each of the 20 common amino acids found in protein molecules has a corresponding type of transfer RNA. Thus, a specific tRNA carries the appropriate amino acid to its appro...

(tRNA) A type of RNA that brings the amino acids to the ribosomes to make proteins. There are 20 kinds of transfer RNA molecules, one for each of the 20 main amino acids. A transfer RNA molecule has an amino acid attached to it, and contains the anticodon corresponding to that amino acid in another part of its structure. In protein synthesis...
