How Do They Repair Damaged DNA Cells? Thus, enzymes known as DNA glycosylases remove damaged bases by literally cutting them out of the DNA strand through cleavage of the covalent bonds between the bases and the sugar-phosphate backbone. The resulting gap is then filled by a specialized repair polymerase and sealed by ligase. How do
Does Base Excision Repair Cut The Dna? Base excision repair (BER) corrects DNA damage from oxidation, deamination and alkylation. Such base lesions cause little distortion to the DNA helix structure. How does the base excision repair pathway recognize DNA damage? In both prokaryotes and eukaryotes, a major cellular mechanism for the removal of DNA damage
