Vedclass · Answer

(B) In gel electrophoresis,$DNA$ fragments are separated based on their size through a sieving effect provided by the agarose gel.To visualize the $DNA$,the gel is stained with ethidium bromide $(EtBr)$.When the stained gel is exposed to $UV$ radiation,the $DNA$ fragments appear as bright orange-coloured bands.Option $B$ is incorrect because chromogenic substrates are typically used in blue-white screening for recombinant colonies,not for visualizing $DNA$ bands in gel electrophoresis.The extraction of $DNA$ bands from the agarose gel is indeed known as elution.
