Diameter of a dna molecule
WebDec 7, 2007 · 14. "Size" of a DNA molecule? Sorry for such a beginner's question in an advanced profile forum: In basic school we were taught that a molecule of a substance is "the smallest structure which still retains all the properties of that substance. If you divide it any further, (at least some of) its properties are gone". 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 ...
