Gel electrophoresis is a technique for separating different protein or nucleic acid molecules from one another in an electrical field. If two molecules are the same size, how would you be able to distinguish between them?

Gel electrophoresis could separate the molecules of equal size on the basis of their charge and shape.

Gel electrophoresis could separate molecules on the basis of their molecular weight only, so you would need to digest them to see a difference.

Gel electrophoresis could separate molecules on the basis of shape, with tightly condensed, globular molecules remaining at the negative end of the gel (at the anode).

Gel electrophoresis could separate molecules on the basis of charge, with positively charged molecules migrating to the positive end (toward the cathode end of the gel).
