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.
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 !

Thank you so much maam ❤️ 🙏 , it's very helpful
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
FACTS
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

I finally understood just by watching your video. thank you so much!
Clear explanation that isn’t overly complex.
Thank you! You explained it 1000x better than my overpriced college did!
Thank you so so so much! Great teacher, much love
I am student from Taiwan.This is a very great video for me to pass the my Genetics exam!👍👍👍
Watching 2days before 3rd year final🤲🫶.
Thank you miss
You’re a great teacher.Thank you ma’am 🙏
THIS WAS SO HELPFUL THANK YOU!!!!
This helps a lot. THANK you so much!
Thank you so much! You explained so clearly!
This is the best video ever you rock thank you
Great! It's well explained. 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!
Thank you so much for solving the exercises in the video! It helped me a lot!
This is super helpful. Thank you!
This was very helpful, very detailed and perfectly explained, so Thank. you!
Wow, you explained this so well! Thank you!
Thank you 😊
Awesome video just awesome
youre an amazing teacher!!
It's very helpful, thank you!
Very helpful to me. Thank you ma'am.
Thank you so much!
Thank you!!!!
I'm here an hour before exam
Thanks ♥️♥️♥️
god bless you

Hi Susan thank you so much for your prompt reply, and thanks again for these great videos!
thank you so much mam
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!

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!
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!
