<prompt> Nucleic acids absorb UV light maximally at the wavelength of260nm280 nm410 nm320 nm  <response>: Nucleic acids absorb UV light maximally at the wavelength of 260 nm 260280 ratio of pure DNARNA is in the range of 1.8 to 2. Amino acids absorb U.V light not visible light- colorless. Aromatic amino acids absorb U.V light at 250-290 nm maximum absorption is at 280nm because of conjugated double bonds.
