Hi everyone. Let's look at our next problem. It says identify the nonsense code on. Let's recall from our content, video that a nonsense code on is one that does not code for an amino acid. And so as a result translation stops at the point of this code on. So it's also called a stop code on. And when I want to look up what code is code for, I look it up in a code on chart. Let's notice that um when we look over our answer choices, all of the code is given two choices A, B and C begin with you and Joyce D is all of the above. So there's a possibility that all of these are the correct answer. So I'm not going to put up the entire code on charts because all the answer choices that I have to look at begin with you. So I'm just going to put up the first row. This is what the first robo code on chart would look like it's written in this format. So over here on the left we have the first letter, the whole chart. You go on down to u c a G. But again I only need um a first letter you here. So I've just got the top row and then the second letter across the top here and then the third letter in four rows within each box. So the code ons I'm looking for here, I have you A so I go to U A and then down here to a and I see that you A is a stop code on. But again, I have that possibility of all of the above, so I'm just going to mark it correct and then check the next thing. Choice B. Is you A. G. That's right here. And that's also a stop code on. So I will mark that is correct. Now, if I were on a test I would just go ahead and choose D. All the above because I've already got more than one correct answer, but I'm just going to be thorough in my explanation here. So the third coat on here is U. G. A. And here it is, and that is also a stock coat on as I would expect. And so yes, the non identify the nonsense code on that would be choice to all of the above. See you in the next video.
