molar absorptivity, ɛ, of double-stranded The weight of proteins or nucleic acids in solution is often determined by UV spectroscopy using the Beer-Lambert law. For example, DNA at 260 nm is 6670 M'cm-'. The formula weight of the repeating unit in DNA (650 Daltons) can be used as the molecular weight. What is the weight of DNA in 4.0 mL of aqueous buffer if the absorbance, measured in a 1-cm cuvette, is 0.35? Choose the correct value from the drop-down list provided. Weight of DNA: v gram

Why do aldehydes, esters, and amides all have a strong absorption in the 1630-1780 cm1 region of their IR spectra? A) The bond between H and the sp³-hybridized C in these functional groups vibrates in this energy range. B) Each of these functional groups has at least two resonance structures, and the different vibrations of the resonance structures give off energy in this region. C) The bond between O and the sp²-hybridized C in these functional groups vibrates at a frequency in this energy range. D) Light at this wavenumber causes the average C to O bond length to increase which causes more of this light to be transmitted. E) An electron in the bond of these functional groups gets excited to the * orbital.
