tRNA

Transfer RNA (abbreviated tRNA), first hypothesized by Francis Crick, is a small RNA chain (73-93 nucleotides) that transfers a specific amino acid to a growing polypeptide chain at the ribosomal site of protein synthesis during translation. It has a 3' terminal site for amino acid attachment. This covalent linkage is catalyzed by an aminoacyl tRNA synthetase. It also contains a three base region called the anticodon that can base pair to the corresponding three base codon region on mRNA. Each type of tRNA molecule can be attached to only one type of amino acid, but because the genetic code contains multiple codons that specify the same amino acid, tRNA molecules bearing different anticodons may also carry the same amino acid.

Noun

Transfer RNA.

transfer RNA, a small ribonucleic chain (74-93 nucleotides) that transfers amino acids to the ribosome to be placed in the order prescribed by the messenger RNA; tRNA molecules match up with a template strand of mRNA to facilitate formation of a specific sequence of amino acids into linear strands that are later processed in the cell to form proteins.
