Base excision repair is a DNA repair mechanism that removes the chemically modified bases from the DNA. The Enzyme involved in Base excision repair is DNA glycosylases. The DNA glycosylases, enzyme removes the modified base to create an AP site. This site is then cleaved by AP endonuclease and repaired by DNA pol I and ligase.
