4 . The imino tautomer of adenine can pair with cytosine
... Nitrous acid (HNO2) hydrolyzes amino groups on bases via diazotization. Adenine is deaminated to hypoxanthine, cytosine to uracil, and guanine to xanthine. Hypoxanthine pairs with cytosine, inducing a mutation of A-T to G-C. It is likely that mutations in DNA repair genes will lead to the accumulati ...
