Which Pair Of Nitrogenous Bases Will Form A Bond In A Dna Molecule? / Complementary base pairs: purine-pyrimidinepairs; sugar ... - A base pair refers to two bases which form a rung of the dna ladder. the 5' and 3' designations refer to the number of carbon atom in a deoxyribose sugar molecule to which a phosphate group bonds. . The chemistry of the nitrogenous bases is really the key to the function of dna. The bases within dna undergo complimentary base pairing with cytosine forming three hydrogen bonds to guanine, and adenine forming two hydrogen bonds to thymine. Rather, each a in one strand always pairs with a t in the. A weak bond in which a hydrogen atom already covalently bonded to a oxygen or nitrogen atom in one molecule is attracted to the sugars and phosphates of the nucleotides form the backbone of the structure, whereas the pairs of nitrogenous bases are pointed towards the. Only two form between a and t because carbon 2 of the adenine base has little more th
