In my clinic’s small electrophoresis unit, the DNA moves to the anode because it carries a negative charge, baba—the phosphate in its backbone sees to that. But I’ve seen old buffers give weak results, making the bands faint, like a tired man’s walk. It reminds me of rewiring my charpoy—the current must flow true, and the material must be sound, or everything drifts aimlessly.
