WebJul 15, 2024 · Chargaff's Rule. Chargaff's rule, also known as the complementary base pairing rule, states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G). A purine always pairs with a pyrimidine and vice versa. However, A doesn't pair with C, despite that being a purine and a pyrimidine.

WebNucleosides are purine and pyrimidine derivatives that have a sugar attached to a nitrogen ring, a hetero-cycle called a heterocyclic base. Consists of a purine or pyrimidine base attached to a pentose. The sugar is linked to a heterocyclic base via a β-N-glycoside bond, almost always to N-1 pyrimidine or N-9 purines.
