WebMar 6, 2024 · The double helix, made up of a pair of DNA strands, has at its core, bases joined by hydrogen bonds to form base pairs - adenine always paired with thymine, and guanine invariably paired with cytosine. Two hydrogen bonds are formed between adenine and thymine, but three hydrogen bonds hold together guanine and cytosine (Figure 2.127). WebJul 15, 2024 · It's bonding between the nitrogenous bases that allows for this structure to form. In DNA, there are four nitrogenous base options: adenine (A), thymine (T), cytosine (C) and guanine (G). Each base can only bond with one other, A with T and C with G. This is called the complementary base pairing rule or Chargaff's rule. The Four Nitrogenous Bases
