Question

Quizplus · Accepted Answer

Termination codons (also known as stop codons) differ from other codons in that they do not code for any amino acid. Instead, they signal the end of the protein synthesis process. Termination codons (UGA, UAG, and UAA) are not recognized by any tRNA molecules, and therefore no amino acid is added to the growing polypeptide chain.
