title: A left-handed supramolecular assembly around a right-handed screw axis in the crystal structure of homo-DNA.
abstract: Duplexes of homo-DNA, a hexose analogue of DNA and autonomous pairing system, exhibit unusual conformational features, and in the crystal structure create a unique double-helical supramolecular motif whose main characteristic is a handedness that is opposite to that of the underlying crystallographic symmetry.
