The separated DNA fragments can be visualized only after staining the DNA with a compound known as Ethidium bromide followed by exposure to UV radiation. Bright orange colour bands of DNA would be seen.

Elution: The separated bands of DNA are cut out from the agarose gel and extracted from the gel piece.
