Preferential removal of bases in pairs that have oxidized guanine is designed to minimize mutations using different Mut system having specific functions match them correctly

Mut system	Mutational pairing
1. MutT	a. removes G=O that is paired with C
2. MutM	b. removes A that is paired with G=O
3. MutY	c. hydrolyzes 8-oxo-dGTP
