In a dna molecule which bases pair together
WebJul 19, 2024 · From Chargaff's rules, the two strands will pair A with T and G with C. This pairs a keto base with an amino base, a purine with a pyrimidine. Two H‑bonds can form between A and T, and three can form between G and C. This third H-bond in the G:C base pair is between the additional exocyclic amino group on G and the C2 keto group on C. WebJul 1, 2024 · Complementary bases engage in hydrogen bonding with one another: (a) thymine and adenine; (b) cytosine and guanine. If two pyrimidines were paired or two purines were paired, the two pyrimidines would take up less space than a purine and a pyrimidine, and the two purines would take up more space, as illustrated in Figure 23.7. 4.
