<prompt> 5-methyl cytosine mutation of DNA DNA methylation leads to:Deamination to thiamine;DNA repairMethylation protects the host DNA from cleavage by its own restriction enzymeAll  <response>: A i.e. Deamination to thiamine; B i.e. DNA repair C i.e. Methylation protects the host DNA from cleavage by its own restriction enzymeDeamination of cytosine forms uracil and deamination of 5 methyl cytosine forms thymine. TDG MBD4 DNA uracil glycosylase remove either U or T residues paired with G, generated by deamination.DNA methylation of adenine at 5 GATC repair mismatched base pairs. And methylated parental template strand is protected from cleavage digestion by its own restriction enzyme.
