The method is rapid, utilizes a helix from a simple list of bonds for basic DNA subunits, and avoids applying successive transformations to obtain coordinates. Deviations from equilibrium values for P03' bond lengths and 05'-P-O3' bond angles at residue connection sites are permitted, thereby avoiding the need for ring closure and geometry optimization. Every dimer building block is constructed from two sets of variables, one for each strand, and assembled into a helix by rigid body transformations. The author suggests how the algorithm can be used not only to generate standard A, B, and Z-DNA helices, but also to set up a wide range of starting conformations for the purpose of identifying novel helical structures. The book concludes by proposing ways the algorithm can be used to apply the build-up technique and pursue a build-up technique, and to explore conformational space systematically. Its insights will be valuable to those seeking to investigate the base sequence/structure relationship.
