Does Base Excision Repair Cut The Dna?

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
