摘要: Abstract Dynamic light scattering in the pretransitional region of I→Ch phase transition deoxyguanosine 5′-monophosphate reveals presence two diffusive modes. The slower mode is assigned to translational motion large spherical aggregates, similar those observed isotropic solutions DNA and other polyelectrolytes. faster stacked arrays guanosine tetramers can be described by polyion diffusion.
