Cells possess several overlapping DNA damage repair pathways that allow them A one-step DNA repair process involving an enzyme that reverts the DNA lesion to the original nucleotides. Examples are 0 6 -methylguanine DNA methyltransferase (MGMT) andphotolyases. MGMT Exclusive Water Damage Restoration Leads - We\'ll Make Your Phone Ring!
