WebAccording to Watson-Crick base-pairing, which forms the basis for the helical configuration of double-stranded DNA, DNA contains four bases: the two purines adenine (A) and guanine (G) and the two pyrimidines cytosine (C) and thymine (T). Within the DNA molecule, A bonds only with T and C bonds only with G. WebDNA uses four kinds of nitrogenous bases: adenine (A), guanine (G) cytosine (C), and thymine (T). RNA nucleotides may also contain adenine, guanine and cytosine bases, but instead of thymine they have another base called uracil (U). Chargaff's rules
