| | [[Category: Van Der Marel GA]] |
| The molecular structure of a nicked dodecamer DNA double helix, made of a ternary system containing d(CGCGAAAACGCG) + d(CGCGTT) + d(TTCGCG) oligonucleotides, has been determined by x-ray diffraction analysis at 3 A resolution. The molecule adopts a B-DNA conformation, not unlike those found in intact dodecamer DNA molecules crystallized in a somewhat different crystal lattice, despite a gap due to the absence of a phosphate group in the molecule. The helix has a distinct narrow minor groove near the center of the molecule at the AAAA region. This suggests that the internal stabilizing forces due to base stacking and hydrogen-bonding interactions are sufficient to overcome the loss of connectivity associated with the disruption of the covalent backbone of DNA.
