If the percentage of adenine (A) in human DNA is 32%, the percentage of thymine (T) would also be 32%.This calculation is based on Chargaff's rules, which state that in a double-stranded DNA molecule, nitrogenous bases always pair in a specific manner:Adenine (A) always pairs with Thymine (T) (A = T).Guanine (G) always pairs with Cytosine (C) (G = C)
