And so we have zero point 97 to the 50th power and that gives us about zero point 22 and that is equivalent to a 22% likelihood. So that's a relatively small likelihood. So what that means is there is a 78% chance that our sequence will not be the correct sequence of amino acids. And so we can see mathematically that's exactly why we cannot use the eggman degradation process on very long polypeptides. So what we conclude is even though the admin degradation process is a very useful process when our amino acids are very short, it becomes pretty inaccurate pretty quickly when our amino acid, when our amino acid number increases in that polypeptide. So how do we solve this problem?
