The number of bonds between the base pairs differs; G-C pairs have three bonds, and A-T pairs have only two. DNA’s capacity to store and transmit heritable information depends on interactions between nucleotide bases and on the fact that some combinations of bases form stable links, while other combinations do not. Weak Chemical Bonds: Organic molecules can interact with other molecules through short-range non-covalent forces. A nitrogen atom can fill its octet by sharing three electrons with another nitrogen atom, forming three covalent bonds, a so-called triple bo Each of the base pairs in a typical double-helix DNA comprises a purine and a pyrimidine: either an A paired with a T or a C paired with a G. These purine-pyrimidine pairs, which are called base complements, connect the two strands of the helix and are often compared to the rungs of a ladder.
