Base excision repair

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.

    you've made a seemingly complicated process very easy to understand, thank you!

    i think N Glycolase does not remove the base it just identifies the wrong base. ap endonuclease cleaves the region and the base will be removed from 5 exonuclease than comes polyemrase one with the base and finally dna ligase to repair the cleavage.

    You think wrong man...glycosylase breaks the n-glycoside bond between the base and sugar

    the animation shows a 3' to 5' DNA pol. but the narration say it was a 5' to 3' DNA pol, so which one is it?

    The overall direction is 5' to 3' but in that instance, the exposed ends are 3'-OH on the left side and 5'-P on the right side.

    if i understand correctly, each nucleotide has a 5 prime end and a 3 prime end. the new nucleotide is added so that its 5 prime connects to the 3 prime of the one before it

    When DNA glycosylases remove modified base then already 3'OH nd 5'P site open so AP endoculease what actually did??🤔🤔

    Nope the phosohodiester bond is not broken as the nucleotide moeity( without the base) still remains at the region..
