WebChargaff’s Rule of Base Pairing. In the Chargaff’s rules of base pairing are: Relation of A with T: The Pyrimidine Thymine (T) always pairs with the Purine Adenine (A) Relation of C with G: The Purine Guanine (G) always pair with the Pyrimidine Cytosine (C) It is steady with there not being enough space (20 Å) for two purines to fit within ... WebChargaff's data show that an approximately 1:1 molar ratio exists between adenine and thymine bases, and between guanine and cytosine bases. Watson and Crick used these data to come up with complementary base pairing, which requires that every adenine pairs with a thymine and every guanine pairs with a cytosine.
