Electrophoresis is a technique used for the separation of substances of different ionic properties. Since the DNA fragments are negatively charged molecules, they can be separated by allowing them to move towards the anode. DNA fragments move towards the anode according to their molecules size through the pores of agarose gel. Thus, the smaller fragments move farther away as compared to larger fragments.
