Vedclass · Answer

(D) Heterocyclic nitrogenous bases (purines and pyrimidines) present in $DNA$ and $RNA$ exhibit a characteristic absorption of ultraviolet $(UV)$ light.This absorption is primarily due to the conjugated double bond systems within the ring structures of these bases.The peak absorption for these nitrogenous bases occurs at approximately $260 \ nm$.This property is widely used in molecular biology for the quantification of nucleic acids using spectrophotometry.

Which one of the following is the peak absorption wavelength of ultraviolet light by heterocyclic nitrogenous bases (in $nm$)?
