Three hydrogen bonds rather than the two of A T, which is why GC rich regions of DNA require more energy to melt and why bacterial genomes vary in GC content as a signature of their evolutionary history. The pendant carries that asymmetry. The Science Behind C G Base Pairing Cytosine pairs with guanine through three hydrogen bonds, while adenine pairs with thymine
