So we know that this is Alanine, and then we repeat it a second time. And now we know it is Arginine. And after we repeat a second time, we're going to get this peptide that contains four amino acids, and we continue it over and over until we get all those amino acids. And this is shown in the following diagram. So once we carry out the admin degradation process the first time, we can repeat this procedure four more times to basically determine the entire sequence of amino acids. And this is shown here.
