A Sample of a Mixture Containing Lysine, Glutamic Acid, Cysteine

A sample of a mixture containing lysine, glutamic acid, cysteine, and histidine is placed on a piece of paper moistened with a solution at pH 5.0 . An electrical field is then applied across the paper to separate the amino acids (electrophoresis) . Starting from a position closest to the anode and proceeding toward the cathode, what amino acids would be encountered?

A) Glu, Cys, His, Lys
B) Lys, His, Cys, Glu
C) Cys, His, Glu, Lys
D) His, Glu, Cys, Lys
E) Cys, Glu, His, Lys
