BIOL183: Solving Lac operon problems

- Опубликовано: 14 авг 2024
- 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.
Watch an introduction to operons and transcription factors here: • BIOL183: Control of Ge...
I have my final exam tomorrow and this has really made Lac Operon and Partial Diploids so much more understandable, thank you!
Deserve million likes 🙏you did what my teacher couldn't do in 6 hours. Thank you soo much

Thank you so much maam ❤️ 🙏 , it's very helpful
Literally had no idea what any of this meant during my lecture but you have explained this in a way that makes complete sense! 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.
THIS WAS SO HELPFUL THANK YOU!!!!
Clear explanation that isn’t overly complex.
I finally understood just by watching your video. thank you so much!
Thank you! You explained it 1000x better than my overpriced college did!
I am student from Taiwan.This is a very great video for me to pass the my Genetics exam!👍👍👍
This helps a lot. THANK you so much!
Great! It's well explained. Thank you
Thank you so much! You explained so clearly!
Thank you 😊
This is super helpful. Thank you!
Thank you so much for solving the exercises in the video! It helped me a lot!
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.
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.
Hi Susan thank you so much for your prompt reply, and thanks again for these great videos!
This was very helpful, very detailed and perfectly explained, so Thank. you!
This was extremely helpful! I am studying for a very competitive genetics exam and this is precisely what I needed after floundering for hours!
Wow, you explained this so well! Thank you!
youre an amazing teacher!!
It's very helpful, thank you!
Thank you so much!
Very helpful to me. Thank you ma'am.
Thank you!!!!
Thanks ♥️♥️♥️
god bless you
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 !
This also comes on my mind that what will be happen?
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!
So will the cell survive if there is z-? Loss of function of LacZ?
Yes - as long as there's something other than lactose to eat!
thank you so much mam
Did they put a marker dna in the plasmid?
In this experiment, I don’t believe there was an antibiotic marker in the F’ plasmid. Today we would definitely include one!
