A-DNA

A-DNA
a double helical structure assumed by RNA-DNA and RNA-RNA chains, or sometimes formed by double-stranded DNA under dehydrating conditions, in which the two chains form a right-handed helix, but more compactly than in B-DNA; there are 11 bases per helical turn, and the stacked bases are tilted. Cf. B-DNA and Z-DNA.
