WebThe sugars and phosphates lie on the outside of the helix, forming the backbone of the DNA; this portion of the molecule is sometimes called the sugar-phosphate backbone. The nitrogenous bases extend into the interior, like the steps of a staircase, in pairs; the bases of a pair are bound to each other by hydrogen bonds.
WebAlso, a pyrimidine is always H bonded to a purine so that the diameter/width of the DNA molecule is consistent throughout the molecule. 2 purines would make the DNA bulky in parts and 2 pyrimidines would make it very narrow. By always pairing a 1 ring base with a 2 ring base the width is constant.
