Vedclass · Answer

(B) In gel electrophoresis,$DNA$ fragments are separated based on their size. Since $DNA$ is negatively charged,it moves towards the anode. These separated $DNA$ fragments are not visible under normal light. To visualize them,the gel is stained with a fluorescent dye called Ethidium Bromide $(EtBr)$. When this stained gel is exposed to $UV$ radiation,the $DNA$ fragments appear as bright orange-colored bands.

In gel electrophoresis,the separated $DNA$ fragments can be visualized by:
