Ethidium bromide binds to nucleic acids by intercalating between bases.When ethidium bromide is irradiated with ultraviolet (UV) light, it fluoresces bright orange.This fluorescence can be visualized with the naked eye by holding a UV lamp over the gel, or with an imaging instrument that shines UV light up through the bottom of the gel.
