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. Additionally, the GC and AT base pairs have ... WebAdenine and guanine are purine bases. These are structures composed of a 5-sided and 6-sided ring. Cytosine and thymine are pyrimidines which are structures composed of a single six-sided ring. Adenine always binds to …
