Comprehensive Bending Classification of Nucleic Acid Double Helix Structures

Structures for which the helical axis is best described by a circular line (arc).
Sigma2 of a circular line (arc) is only slightly smaller (< 0.2) than for the next best model(s). The structures are listed by the number of base pairs (bp).
