The features of the DNA (deoxyribonucleic acid) molecule thatallow it to form the distinctive Z-DNA structure, containingzig-zag conformation of phosphate groups. Introduction: The first double-helical structure of DNA, discovered by Watson and Cric, ks known as B-DNA. DNA can form different conformations because deoxyribose sugar is flexible and the C’-N-glycosidic linkage can rotate. Z-DNA (Helix diameter of 1.84nm) is the Z form of DNA, which is slimmer than the B form of DNA.
