Figure 11: Temperature-dependent CD and NMR spectra.
From: A tetrahelical DNA fold adopted by tandem repeats of alternating GGG and GCG tracts
(a) CD spectra of VK1 construct were recorded at 0.8 mM concentration per strand in a 0.01-cm path-length cell at 100 mM LiCl, pH 6 and different temperatures indicated by different colours. (b) 1H NMR spectra of VK1 at 2.8 mM concentration, pH 6 and different temperatures indicated next to individual spectrum. (c) The enlarged region characteristic for imino protons of G-C base pairs in Watson–Crick geometry in spectra recorded at 0, 30 and 40 °C.
