1H NMR investigation of the conformational states of DNA in nucleosome core particles.

In this study 1H NMR has been used to investigate the conformational state of DNA in nucleosome core particles. The nucleosome core particles exhibit partially resolved low field (10-15 ppm) spectra due to imino protons in Watson-Crick base pairs (one resonance per GC or AT base pair). To a first approximation, the spectrum is virtually identical with that… CONTINUE READING
