This guy has been helping since I was a freshman in high school... I am now about to graduate college

[chidinmaosuagwu]

can not believe how much more helpful you are than my professor. god.

[bobaxxful]

sal from khan academy makes me feel safe

[AussieBoganLife]

This helps me understand the LAC OPERON very well without bordering reading whole Campbell 10th edition textbook.

[asimlamichhane]

you just compressed 3 of my agonizing lectures into 11 minutes and now i've understood it all. You are my hero.

[usmanshami]

I love this guy. Whoever is the narrator. Amazing explanation. He just made lipincott so easy. Khan Academy is the best. Always listen to it literally for every topic

[raanoooshh]

Thanks for this video! Great explanation! One thing to add for those who are curious is that when glucose levels are high the RNA-polymerase will bind to a promoter (not the same promoter) and transcribe a gene that codes for a repressor so that in turn can bind to the operator and stop transcription of the beta-galactosidase (LacZ) since we don't need to metabolize lactose.

I used to watch your videos in high school/mcat. Now im months away from my usmle step 1 in final year of medical school and youre still helping me. Thankyou

[haseebs]

Thank You Khan Academy, What took Hours of Learning you taught in 11 minutes, Thanks!

[musicgirl]

This is so much better than trying to read from the Lehninger Principles of Biochemistry textbook. I read every word about the lac operon, but did not understand any of it until this video. THANK YOU

[steph]

I decided to take Microbiology over the summer, for the 6 week term. I don't even bother listening to my lectures anymore because they are so confusing and overly complicated. I just use my book along with Khan Academy. I will be making a donation!

[stafinaartist]

I referred your videos for taking a biology seminar at my school and i got an A+, thank you khan academy.

[isaacgraber]

Unbelievably helpful, took a concept that I wasn't understanding from lecture and made it make so much sense

[srishtigupta]

This is the first time I actually completely understood the chapter of molecular inheritance, thank you so much khan academy

[yasminamin]

Yesterday, I went to my professor to ask him this exact question. I wish I didn't go. this video. saved my life.
Thank you so much

[Sophie-wpcf]

Especially that you explained the cAMP was very helpful. I'm german and I didn't find anything about it in german videos. Thank you!

[bethanythuringer]

This was one of the best explanations of the lac operon I've heard

[jatinjaggi]

sir there are no words to say for your effortless work I have so much respect fr u KEEP INSPIRING !!

[sirthugbert]

I am a MS2. This video still teaches it better than my biochem or microbio prof. Thank you!

[reyna]

I love this man. I love his personality and the fact that this stuff is less boring and more easy to understand now.
