WebThese latter enzymes link amino acids to their cognate transfer RNAs (tRNA) in aminoacylation reactions that establish the connection between a specific amino acid and a nucleotide triplet anticodon embedded in the tRNA. Therefore, they are the enzymes that translate the genetic code in vivo. WebExpert Answer. A) The enzyme aspartyl-tRNA synthetase catalyzes the activation of aspartic acid (compound 1) to form aspartyl-AMP (compound 2) and then the conjugation of aspartic acid to the tRNA.
