why does exposing DNA fragments move when exposed to a charged environment?

DNA gel electrophoresis is a technique used for the detection and separation of DNA molecules. An electric field is applied to a gel matrix comprised of agarose, and within the gel, charge particles will migrate and separate based on size. The negatively charged phosphates of the DNA backbone cause DNA fragments to move toward the anode - a positively charged electrode.

 If a voltage is applied across the agarose slab, the negatively charged DNA fragments will move through the agarose gel toward the positive electrode.
