Which of the following statements concerning demethylation of the genome are correct? Select all that apply. Deamination of methylated cytosine produces thymine. Deamination of unmethylated cytosine produces uracil. Loss of DNMT3 activity would cause demethylation of the genome over time in replicating cells. Loss of DNMT1 activity would cause demethylation of the genome over time in replicating cells. Hydroxymethylation of methylated cytosines is the primary manner in which demethylati...
