Electrophoresis - is the seperation of molecules using an electrophoretic field.  Molecules move in the field based on charge and relative mobility.

DNA molecules, which are negatively charged (anions) migrate to the anode.  Their movement to the anode is controlled by the pore size in the gel (agarose) matrix.
