Q. A mixture contains three similarly sized peptides P, Q and R. The peptide P is positively charged, Q is weakly negative and R is strongly negative. If this mixture is passed through an ion-exchange chromatography column containing an anionic resin, their order of elution will be
(A) P, Q, R
(B) R, Q, P
(C) Q, R, P
(D) P, Q and R elute together
Ans: R, Q, P
