Ultraconserved Gene Regulatory Blocks. Non-B DB | ABCC. Please note that non-B DB has been updated to Version 2.0 on Wednesday, June 13, 2012 . To learn more about v2.0, please visit FAQ. If you have any questions, please feel free to contact us. DNA exists in many possible conformations that include the A-DNA, B-DNA, and Z-DNA forms; of these, B-DNA is the most common form found in cells. The DNAs that do not fall into a right-handed Watson-Crick double-helix are known as non-B DNAs and comprise cruciform, triplex, slipped (hairpin) structures, tetraplex (G-quadruplex), left-handed Z-DNA, and others. The Advanced Biomedical Computing Center (ABCC) has systematically identified in several mammalian species the genomic regions predicted to form each non-B candidate structure and placed these into non-B DB.
