Show how electrophoresis can separate glutamic acid (PI 3.2), lysine (PI 9.7), and glycine (PI 6.0) from a solution having pH 6.

• A. Glutamic acid will migrate towards the anode, lysine will migrate towards the cathode while glycine will not migrate.
• B. Glutamic acid will migrate towards the cathode, lysine will migrate towards the anode while glycine will not migrate.
• C. Glycine will migrate towards the anode, lysine will migrate towards the cathode while glutamic acid will not migrate.
• D. Lysine will migrate towards the anode, glycine will migrate towards the cathode while glutamic acid will not migrate.

Answer: (A)
