The DNA fragments having shorter size than other move faster than other. ... DNA samples are loaded into wells at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode

Because all DNA fragments have the same amount of charge per mass, small fragments move through the gel faster than large ones.
