Received October 14, 1980. Coordinates are presented for a refined model of the side-by-side (SBS) structure for the in vivo B-form of duplex DNA. Bond lengths and bond angles are within 0.025Å and 2.0° of standard values and there are no non-bonded intramolecular contacts shorter than 2.75Å. These and other details of the refined model indicate that the SBS proposal is stereochemically viable.
