  • This unnecessarily long video was created for BIOL183 (Spring 2020). Here, we discuss Jacob and Monod's partial diploid E. coli, and also what we can learn about trans-acting and cis-acting factors in regulation of gene expression.

    I have my final exam tomorrow and this has really made Lac Operon and Partial Diploids so much more understandable, thank you!

    Thank you very much😍, my professor didn't teach the lactose operon mutation in university, but now I understand the topic completely after watching this video.

    Thank you for this amazing video! May I ask from which book the illustrations are taken from? I'd like to read more and I struggle to find materials about gene regulation problems such as these.

    • @SciEdSusan
      @SciEdSusan  Год назад +1

      Hi Faissal, these images are primarily from Pierce Genetics published by Macmillan. Similar illustrations are in Campbell Biology, Alberts Cell Biology, and most other Cell/Molecular/Genetics texts.

    thank you so much for this video but I have a question imagine if the promoter ( P-)have a mutation for a diploid problem what is gonna happen if all the other factor ( I,O,Z & Y ) are not mutated ? Does the promoter have a Cis configuration as the operator ? For my opinion, if the promoter is mutate that mean the ARN Pol can not be fix into the promoter = no transcription can be made !

    • @jyotismita5409
      @jyotismita5409 2 года назад

      This also comes on my mind that what will be happen?

    • @SciEdSusan
      @SciEdSusan  Год назад +1

      You are totally correct Miriam! If the promoter is mutated, then RNA Pol won't ever be recruited to turn on transcription, with or without lactose!

  • @primeavatar0403
    @primeavatar0403 Год назад

    So will the cell survive if there is z-? Loss of function of LacZ?

    • @SciEdSusan
      @SciEdSusan  Год назад

      Yes - as long as there's something other than lactose to eat!

    Did they put a marker dna in the plasmid?

    • @SciEdSusan
      @SciEdSusan  3 года назад

      In this experiment, I don’t believe there was an antibiotic marker in the F’ plasmid. Today we would definitely include one!
