Welcome back. Let's look at our next problem based on the three short segments of fox P. Two proteins of four animal species. By how many amino acids does this Z. Finch sequence differ from the mouse sequence. So we're gonna go ahead and highlight our two sequences. Were looking at the the finch and the mouse. And then we want to look for look at their amino acid sequences given here and see where which ones differ and how many. So we look at this first segment and there's no difference. Second segment also the same for both. In the third segment we see that the very last amino acid is different. So looking at our answers, um only one amino acid is different between the two sequences. So our correct answer here is choice A one. So again just one amino acid difference between the finch sequence and the mouse sequence giving us choice A for our answer. Thanks for watching. See you in the next video.
