A hydrogen bond is the electrostatic attraction between polar groups that occurs when a hydrogen (H) atom bound to a highly electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F) experiences attraction to some other nearby highly electronegative atom. Hydrogen Bonds in DNA. The geometry of the hydrogen bonding interaction between DNA and minor-groove binding drugs has been analyzed from a sample of 22 crystal structures of DNA-drug complexes, retrieved from the Nucleic Acid Database. DNA and proteins are held together in their defined three-dimensional structures primarily by hydrogen bonds.
