Video transcript

Hi everyone Next, we'll look at the question based on the sequence alignment of the different species, in how many amino acids from sequences 10 to to frog and fish differ. So we have our different amino acid sequences here. I'm first going to find frog and fish there down at the bottom here And then I want to remember that. It's asking me only to look at sequences 10-15. So I'm going to highlight that here so that I don't um accidentally look at the whole sequence or too far here and then it says, and how many of these amino acids are they different? So we'll look at this segment here and highlight in red, the areas where the amino acids are different. So the first two columns are the same. The third is different and then the fifth over here has different amino acids. So in just that segment of 10 and 15 we see that there are just two different amino acids. So our answer choices. C. Two. So that was a pretty straightforward question. And we'll see you in the next video

Use a highlighter to color any amino acid that varies among the species. (Color that amino acid in all sequences.) e. Primates and rodents diverged between 60 and 100 million years ago, and chimpanzees and humans about 6 million years ago. Compare the amino acid differences between the mouse and the C, G, R species with those between the human and the C, G, R species. What can you conclude?
