The results of X-ray diffraction studies of poly(dA).poly(dT) have been compared with the results of energy optimization and with the NMR data in solution. Slight refinement of the X-ray and energetically optimal models leads to a very good quantitative agreement with the NMR data, that suggests similarity of the poly(dA).poly(dT) structure in a condensed state and in solution. One of the features distinguishing these models from the classic B form is a narrowed minor groove of the double helix. The anomalous properties of DNA with this sequence can be related specific organization of the water molecules near the polynucleotide.
