Final answer:
Aminoacyl-tRNA synthetases play a critical role in interpreting the genetic code by attaching the appropriate amino acid to tRNA molecules.
Step-by-step explanation:
Aminoacyl-tRNA synthetases are enzymes that play a critical role in the process of translation and are involved in interpreting the genetic code. These enzymes are responsible for attaching the appropriate amino acid to the corresponding tRNA molecule according to the codon present in the mRNA. By doing so, aminoacyl-tRNA synthetases ensure that the correct amino acids are incorporated into the growing polypeptide chain during protein synthesis.
