DNA in a solution is negatively charged; if you ran a sample of DNA, what would you predict about its migration?

Assuming that you ran the DNA sample on an agarose gel. And that you are performing gel electrophoresis. I would predict the sample of DNA moving away from the negative terminal or end and to the positive one. As it is being repelled due to its overall negative charge and thus attracted to the positive end. Both the magnitude of charge and size of DNA sample fragment act as factors and contribute to migration.
