The structure of sodium thymonucleate fibres. I. The influence of water content

Abstract

A qualitative survey by Franklin & Gosling of the types of X-ray diagram given by highly orientated specimens of NaDNA at different humidities is reported. The structural changes which occur in NaDNA fibres when their water content is varied suggest that the fundamental structural unit is a group of molecules so arranged that the phosphate groups are exposed and accessible to water.
