Question

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).
