What effect would the deamination of 5-methylcytosine in a promoter have on the expression of that gene?
A) The gene will have increased expression because this chemical reaction will result in unmethylated cytosine.
B) The gene will have increased expression because this chemical reaction will result in thymine.
C) The gene will have increased expression because this chemical reaction will result in uracil.
D) The gene will have decreased expression because this chemical reaction will result in unmethylated cytosine.
E) The gene will have decreased expression because this chemical reaction will result in uracil.
