Homework Answers
5.) A
Sequence A has more hydrophobic amino acids as compared to other sequence, so on the basis of hydrophobicity , this sequence would be the last to elute out.
6.) B
Anion exchange chromatography , means matrix is anion exchanger ( has + charge) , and it binds to anion.
Sequence B would be the last to elute because it has more amino acids which has negatively charged side chains.
7.) E, this is correctly marked.
