Vedclass · Answer

(B) In agarose gel electrophoresis,$DNA$ fragments are separated based on their size. $DNA$ molecules are negatively charged and are not visible under normal visible light. To visualize the $DNA$ fragments,the gel must be stained with a fluorescent dye such as ethidium bromide $(EtBr)$. Once stained,the $DNA$ can be observed as bright orange-colored bands when exposed to $U.V.$ radiation. Therefore,the correct statement is that $DNA$ can be seen with staining in $U.V.$ radiation.

Which of the following statements is correct in the context of observing $DNA$ separated by agarose gel electrophoresis?
