Vedclass · Answer

(B) In the process of gel electrophoresis,$DNA$ fragments are separated based on their size. To visualize these $DNA$ fragments,the gel is stained with a fluorescent dye called ethidium bromide $(EtBr)$. When this gel is exposed to ultraviolet $(UV)$ radiation,the $EtBr$ intercalates into the $DNA$ and fluoresces. Consequently,the $DNA$ fragments appear as bright orange-colored bands under $UV$ light.

When $DNA$ fragments stained with ethidium bromide are viewed under $UV$ radiation,how do they appear?
