<span>All are mutagenic because they cause base substitutions, deaminating agents oxidatively deaminate bases so cytosine converted to uracil and adenine converted to hypoxanthine, uracil pairs with adenine and hypoxanthine pairs with cytosine, alkylating agents donate alkyl group to amino or keto groups altering base pair affinities</span>
