For hydrated DNA, the B-form is favored over the A-form, which is only observed in dehydrating conditions (44, 45). In contrast, dsRNA adopts only the A-form, because the B-form leads to steric clashes of the 2′-OH groups.

WebD. Huttner, I.D. Hickson, in Brenner's Encyclopedia of Genetics (Second Edition), 2013 Helicases are conserved enzymes that hydrolyze adenosine triphosphate (ATP) in the presence of nucleic acids.
