what is electrophoresis
Electrophoresis is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field.his is used for both DNA and RNA analysis. Polyacrylamide gel electrophoresis (PAGE) has a clearer resolution than agarose and is more suitable for quantitative analysis. In this technique DNA foot-printing can identify how proteins bind to DNA. It can be used to separate proteins by size, density and purity.
