transfer rna meaning

Noun: transfer RNA

1. 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)
   - tRNA, acceptor RNA, soluble RNA

Type of: ribonucleic acid, RNA

Encyclopedia: Transfer RNA

[Medicine]
The small RNA molecules,73-80 nucleotides long,that function during translation (TRANSLATION,GENETIC) to align AMINO ACIDS at the RIBOSOMES in a sequence determined by the mRNA (RNA,MESSENGER). There are about 30 different transfer RNAs. Each recognizes a specific CODON set on the mRNA through its own ANTICODON and as aminoacyl tRNAs (RNA,TRANSFER,AMINO ACYL),each carries a specific amino acid to the ribosome to add to the elongating peptide chains.n : a relatively small RNA that transfers a particular amino acid to a growing polypeptide chain at the ribosomal site of protein synthesis during translation —called also adapter RNA, oluble RNA, RNA —compare MESSENGER RNA
