And once again, you isolate the three fragments and you sequence the amino acids in those three fragments by using the ethnic degradation process. And you find that fragment number one is lysine, aspartate, serene. Fragment number two is glycine tryptophan, and fragment number three is arginine and tyrosine. So now that you have these six different fragments, so you have two sets of fragments, you want to use the overlapping regions of the fragments to basically sequence these fragments in the correct order with respect to one another. So let's begin on this fragment here. So we have glycine, tryptophan, arginine.
