    oh my God.
    i am from non-biology background.
    cannot believe our human has this jaw opening cellular dna mechanism.
    amazing how this was even discovered.
    thank you

    Ap Endonuclease cleaves the 5’ end .. and Lyase cleaves the 3’ end .. then DNA polymerase and DNA lygase play role.
    You forgot to mention the Lyase part!
    “Base-specific Glycosylase removes altered base and creates AP site (apurinic/apyrimidinic). One or more nucleotides are removed by AP-Endonuclease, which cleaves the 5′ end. Lyase cleaves the 3′ end. DNA Polymerase-β fills the gap and DNA Ligase seals it. Occurs throughout cell cycle.” GEL PLease! (The steps gylcosylase, endonuclease, lyase, polymerase, ligase)
    The quote is from FA USMLE step 1, biochemistry section (2 section), page 40.

  • @JS-hh9zs

    One question though. How the DNA glycosylase know which base (in this case uracil), are the wrong uracil. After all, there are uracil also in immature mRNA. Why don't the glycosylase also cut the uracil from the right nucleotide? how it recognize the wrong uracil?

      @@ComandaKronikk Actually apyrimidine site is very rare since it requires high acidity to cleave off the pyrimidine from the site where as Apurine site is easily formed in the cell at lower acidity or even under neutral pH.
      that is why your Professor has told u it is mostly Purines.
