What Is The Difference Between Gel Electrophoresis And Paper Chromatography?

Paper chromatography is an analytical technique for separating and identifying mixtures that are or can be colored and agarose gel electronphoresis is a method used in biochemistry and molecular biology to separate DNA, DNA or molecules by size. This is achieved by moving negatively charged nucleic acid molecules through an agarose matrix with an electric field (electrophoresis) shorter molecules move faster and migrate farther than longer molecules.
