Abstract
A method of analyzing a DNA molecule is disclosed. In one embodiment the method comprises the steps of exposing a DNA molecule to an effective amount of a chemical modification reagent wherein the reagent converts guanine to 8-hydroxyguanine. The oxidized product is then exposed to a DNA glycosylase enzyme and the DNA molecule is cleaved at the site of the 8-hydroxyguanine. The fragments are then resolved by electrophoresis and the position of guanine residues within the DNA molecule is determined. In a preferred embodiment of the present invention, the modification reagent is a thiazine dye and the enzyme is FPG protein.
