  • Thank you so much for pointing out the mistake.
    Correction: In Eukaryotes, the leading strand is synthesized by DNA polymerase epsilon.
    After initial priming by DNA polymerase alpha, DNA polymerase delta takes over the synthesis on the lagging strand (Lata Balakrishnan and Robert A. Bambara, JBC, 2011; 286(9): 6865--6870)

    Pol epsilon --> leading
    Pol delta --> lagging

    Pol Epsilon in Leading and Pol Delta in Lagging, also Pol alfa + Fcn1 or DNA 2 take out Primers

    At 1:17 there are enzymes and proteins. You circled a bunch of so called proteins. But on google they are also enzymes. Like Ligase. Can you explain the discrepancy?

    • @biologyexams4u
      @biologyexams4u  3 ปีที่แล้ว

      Hi Nancy
      Really appreciate your Question...The point is generally speaking all enzymes are proteins (with some exceptions like ribozymes). But all proteins are not enzymes. Lets take an example from DNA replication itself
      Enzyme eg: The formation of a phosphodiester bond is catalyzed by enzyme DNA polymerases.
      Protein only Eg: Tus protein, also known as terminus utilization substance, is a protein that binds to terminator sequences effectively blocks DNA polymerase movement causing termination.
      Hope you are clear..
