Title: How many tri-peptide sequences can be formed from these residues/? Post by: junior26 on Nov 10, 2012 Given residues: Glycine, Alanine and Phenylalanine.
Is there a mathematical expression that allows us to calculate the total number of Sequences? Thanks, all help is appreciated. Title: How many tri-peptide sequences can be formed from these residues/? Post by: Bungalo on Nov 10, 2012 You have three amino acids so the possible number of permutatioins (combinations) is
3! which is 1 x 2 x 3 = 6 The exclamation mark stands for "faculty n! = 1 x 2 x 3 x 4.......x n" GAP...........AGP............ .PAG GPA............APG........... .PGA |
