Question:

Oxidation of DNA bases is mutagenic. An oxidized form of guanine, 8-oxoguanine, can base-pair with adenine, leading to errors in DNA replication. A gene called mutT acts to minimize the tendency of A-oxoG base pairs to form. The mutT gene product was purified and shown to be an enzyme. Speculate on the reaction catalyzed by this enzyme.
