Answer
Each tRNA is paired with a correct amino acid because of the work of a group of enzymes called aminoacyl-tRNA synthetases. Each of these enzymes is specific for the amino acid and its corresponding tRNA. The reaction uses ATP to form a high-energy bond between the amino acid and the tRNA. This energy will later be used in the formation of peptide bonds between amino acids in an elongating polypeptide chain.
