The concept defines the biochemical mechanism of complementary base pairing within nucleic acid structures, governed strictly by Chargaff's rules and hydrogen bonding specificity between adenine-thymine and cytosine-guanine pairs. It establishes a deterministic correspondence where purines exclusively pair with pyrimidines to maintain consistent helical geometry, forming the foundational stoichiometric constraint for double-stranded nucleic acid topology. This theoretical framework operates within molecular genetics and biochemistry as a fundamental axiom describing the structural stability and information storage capacity of nucleic acid polymers.
The core principle governing nucleic acid architecture is complementary base pairing within DNA poly nucleotides, where nitrogenous bases pair specifically via hydrogen bonds: cytosine exclusively wi…
