Question

Use a highlighter to color any amino acid that varies among the species. (Color that amino acid in all sequences.)
c. The O sequence differs from the C, G, R sequences at one amino acid (having V instead of A) and from the H sequence at three amino acids. Identify the O sequence.

Accepted Answer

Hi everyone. Next we'll look at the question based on the sequence alignment of the different species, what amino acid in sequence 14 does the frog have? Which differs from the rest of the given species. So I have a short sequence of amino acids from protein found in five different species, including the frog. And I want to look at the amino acid in sequence 14. So the amino acids here are given by their one letter code. And I will highlight here, sequence 14 to make it easier to spot the difference. And we can see that indeed, while the other species have amino acids symbolized by Q. Frog as amino acids symbolized by K. When we looked at our answer choices, it's the full name of the amino acids. So at this point I'd want to look up either in my textbook or if this was a text, I'd expect that they'd have a chart provided of the amino acids and their one letter symbols here. So I can look along and see the names of the amino acids and one letter symbol. So we're looking for. Kay. And that is the amino acid lysine. So when we look over at our answer choices, we see that we have a praline beam, Athenian C. Phenylalanine and D. Licensing. So we know that D must be our correct answer. We can just double check the others. Make sure that we can eliminate them. We see that praline is P. Matthias is M and federal indian is F. So again, are correct choices. D licensing.
