DNA containing alternating purine and pyrimidine repeat tracts have the potential to adopt this non-B structure in vivo under physiological conditions, particularly in actively transcribed regions of the genome. A-DNA is one of the possible double helical structures which DNA can adopt. A-DNA is thought to be one of three biologically active double helical structures along with B-DNA and Z-DNA. It is a right-handed double helix fairly similar to the more common B-DNA form, but with a shorter, more compact helical structure whose base pairs are not perpendicular to the helix-axis as in B-DNA.
