The first rule holds that a double-stranded DNA molecule globally has percentage base pair equality: %A = %T and %G = %C. They were discovered by Austrian-born chemist Erwin Chargaff, … Thus, amount concentration of guanine is equal to cytosine and adenine is equal to thymine. Chargaff's Rule of Base Pairing The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G) .
