So there should be a bond connecting Arginine and Glycine. And by using this region here and this region here, we can basically determine where these two fragments go. So Serene and Phenylalamine should basically go here. And Alanine Lysine should basically go here. So we have our Serine, Phenylalanine, and then here we have Alanine, Lysine. And so the final sequence is so we have Serine, Phenylalalanine.
