Deoxyribonucleotides form a double-helix polymer composed of antiparallel polynucleotide chains where deoxyribose sugars and phosphate groups create the structural backbone via phosphodiester linkages, while nitrogenous bases project internally to facilitate Chargaff's rule of complementary base pairing. This structure is defined by specific hydrogen bonding interactions between purines (adenine, guanine) and pyrimidines (thymine, cytosine), establishing a mechanism where A-T pairs form two bonds and G-C pairs form three bonds within the central helical architecture. The theory distinguishes functional roles of these strands in transcription through coding versus non-coding orientations while maintaining genomic stability provided by histone protein attachments.
