title: Ultra-high resolution DNA structures.
abstract: This paper describes the progress in our efforts at producing ultra-high resolution (< 0.8 A) DNA structures using advanced cryo-crystallography and synchrotron. Our work is aimed at providing reliable geometric (bond length and bond angle), electronic and motional information of DNA molecules in different conformational contexts. These highly-reliable, new structures will be the basis for constructing better DNA force-field parameters, which will benefit the structural refinement of DNA, protein-DNA complexes, and ligand-DNA complexes.
