The DNA fragments separated on an agarose gel can be visualized after staining with Ethidium bromide, Bromophenol blue, Acetocarmine, Aniline blue?

Agarose gel electrophoresis is used to segregate DNA fragments according to the mass and size. Ethidium bromide is the fluorescent stain used in this technique. Ethidium bromide, when exposed to ultraviolet light, produces a fluorescent effect. Hence the DNA tagged by it can be traced quickly on the transparent gel. Thus the correct answer is option A.
