What is the significance of codon-anticodon pairing in the process of protein synthesis?

Codon-anticodon pairing is crucial in protein synthesis because it ensures that the correct amino acid is added to the growing protein chain. The codon on the mRNA molecule must match with the complementary anticodon on the tRNA molecule to bring the right amino acid. This accurate pairing is essential for the proper sequence of amino acids in the protein, which ultimately determines its structure and function.
