Find out correct statement w.r.t DNA structure.
The backbone of a polynucleotide chain is formed due to sugar and phosphates. The nitrogenous bases linked to sugar moiety project from the backbone. The two chains of B-DNA are coiled in a right-handed fashion. The plane of one base pair stacks over the other in double helix. This, in addition to H-bonds, confers stability of the helical structure. Examples of nucleosides include deoxycytidine, deoxyguanosine, deoxythymidine, and deoxyadenosine.
