Which bases has double and triple hydrogen bond

Doublestranded DNA consists of two polynucleotide chains whose nitrogenous bases are connected by hydrogen bonds. Within this arrangement, each strand mirrors the other as a result of the antiparallel orientation of the sugarphosphate backbones, as well as the complementary nature of the AT and CG base pairing. , doublestrandedDNA, genetics, hydrogenBonds, sugarphosphateBackbones
