摘要
We report on synchrotron-based high-angle X-ray solution scattering measured to 2 Å resolution for two synthetic DNA sequences for which there are conflicting X-ray crystal and solution NMR models. Our results demonstrate that high-angle X-ray scattering discriminates between differing X-ray crystal and NMR models for solution-state DNA and provides a direct, independent method for testing structural models and measuring solution-state configurational dispersions.
