And then the ribosome essentially reads every codon one at a time in a sequential manner until we reach this stop codon, UAA. Now, once we reach UA, the release factors bind onto the UAA sequence and that causes the dissociation of this polypeptide chain. So this is the first amino acid. And then we have many other amino acids. And this is the final amino acid that contains that carboxyl terminal group. And once we reach this, this essentially dissociates the polypeptide chain associates from the mRNA molecule and from that ribosome.
