Quaternion modeling of the helical path for analysis of the shape of the DNA molecule by A. F. Muterko

“…Although dual quaternions are preferable for  modeling of DNA structure in detail, the use of unit quaternions is sufficient to predict the DNA trajectory and all calculations of DNA shape features. In order to analyze DNA shape and chain sta ­ tistics, and predict the micromechanical properties of DNA molecules based on coordinates of the helical path, the widely used as well as original algorithms for computing DNA curvature, radius of gyration, persistence length and phasing of DNA bends are described. …”
