Electrophoresis is the movement of scattered particles in respect to a liquid affected by a spatially uniform electric field.It is the  method for separation and analysis of macromolecules (DNA, RNA and proteins) and their fragments, based on their size and charge.Electrophoresis of emphatically charged particles (cations) is here and there called cataphoresis, while electrophoresis of contrarily charged particles (anions) is some of the time called anaphoresis.
