Reactions such as oxidation or deamination can alter dna bases. after replication, these changes may result in point mutations. for example, if cytosine undergoes deamination to yield uracil, the original c: g base pair may be altered to t: a. (c base pairs with g, but u pairs with
a. uracil is recognized and \"corrected\" to t, leading to the t: a pair.) two dna modifications are shown below. label each change as an oxidation or a deamination, place the appropriate molecule in each reaction, and determine the resuting point mutation (nucleotide substitution).
