Molecular modeling has been used to predict that 2,6-disubstituted amidoanthraquinones, and not the 1,4 series, should preferentially interact with and stabilize triple-stranded DNA structures over duplex DNA. This is due to marked differences in the nature of chromophore-base stacking and groove accessibility for the two series.
WebRecent studies have shed new light on the question of what physical forces cause a polymerase enzyme to insert a nucleotide into a strand of DNA and to choose the correct nucleotide over the incorrect ones.

WebG-C has 3 H-bonds while A-T has 2 H-bonds. More bonds generally = more stronger. This is because you'll need more energy to break 3 bonds than 2 bonds. I think the article mentioned about base stacking too. If we ignore the effects of hydrogen bond between complementary base pairs, GC rich sequences are still more stable.
