Which type of RNA is attached to specific amino acids?
A tRNA that has an amino acid attached to it is known as charged tRNA. Chemically bonded to its own amino acid, aminoacyl-tRNA (also known as aa-tRNA or charged tRNA) is one kind of tRNA (charged). The aa-tRNA and other elongation factors transport the amino acid to the ribosome where it is incorporated into the growing polypeptide chain. In order to chemically bond to its associated tRNA, each amino acid has its own aminoacyl-tRNA synthetase. To ensure that only the amino acid whose anticodon matches the tRNA’s anticodon and whose codon matches the mRNA’s codon is used during protein synthesis, the tRNA must be paired with its cognate amino acid.
