This work describes the investigation of the space organization of DNA compact forms and DNA–protein complexes by the small‐angle x‐ray scattering method. A plane texture was disclosed in dehydrated DNP films. Compact DNA particles formed in the presence of poly(ethylene glycol) reveal ordered structures having a periodicity of 84 Å. Various morphological forms of crystals of CTA‐DNA were used to obtain small‐angle x‐ray patterns of the single‐crystal type.
