The dinucleoside phosphates ApU and GpC form right-handed anti-parallel double helical fragments within their crystal lattices. Using a least squares procedure, we have generated the extended double helices which these fragments represent. ApU corresponds to a double helix with 11.9 residues per turn and a pitch of 28. 1Å. The GpC double helix has 10.4 residues per turn and a pitch of 26. 9Å.
