  • Your videos have helped me a lot, thankyou :)

  • i dont really understand the last part of ur video with gene regulation in humans can u please help?

    Are the transcription factors made by the regulator genes? then do the transcription factors bind with the promoter which allows RNA polymerase to attach to the promoter, then the DNA folds back on its self to activate the RNA polymerase so it can make mRNA? sorry just got a bit confused..

  • yeah, can you just be my teacher?!? thank you so much!!! this made everything make sense!!!

  • Great Explanation!

  • Oh my god. You just saved me on my test. THANK YOU.

  • Very very helpful thank you <3 if you charged, I would totally pay you.

  • I get it now thank u

  • awesome vid

  • RNA polymerase needs to GET IT IN baby

  • you're awesome hehe!

  • That was very useful!!! Thank you! These video are great!

  • Awesome ! this video helped me alot. I understand much better know wohoooo :D

  • This video, is fabulous.

  • tomorrow is my test i think i had a grip on this. thanks to you!

  • You're video was extremely helpful thank you for putting of up... :)

  • thank you, really helped video..especially two days before exam :)

  • Thanks! This Helped ALOOOT!!! ;)

  • As a student going for a masters in biochemistry I couldn't do without videos like these. In other words yes it was very helpful.

  • this mother fucker should be my biology teacher

  • LAC operon is negative control because it prevents transcription by a repressor binding :/

  • 5 biology teachers are jealous that Mr. Andersen can teach and they can't.

  • fast and easy way to understand the concept! great! thank you so much!

  • this guys my teacher in real life for AP Bio...hes so great, its my favorite class of the day.

  • @ImTheSleepless You lucky son of a b*tch turns out watching this video helped more then 2 lessons at school...gosh

  • screw notes, i got youtube

  • Having a test in 1 hour on this....GOOD MAN!

  • Thank you. But when am i ever going to use thing is life?

  • @roflwilwin when you drink milk :P

  • @roflwilwin when you have a biology test that is about gene regulation

  • Thank you really helpful thanks for uploading

  • I'm glad I found this vid.. save me from reading those crap..

  • thanx... this is really very helpful.....

  • omg thank you so much I was reading my textbook and it was not making sense at all. now I understand!

  • you are the fkn man,,, thank you,

  • Very helpful:)

  • YOU ARE AN EXCELENT TEACHER THANK YOU MR. PROTEIN I LOVE YOU

  • this is fantastic. thank you

  • Very good job! THANKS!

  • Thanks very much. This really helped me understand the regulation of genes

  • 10,822 views, and 28 comments. That's crap. You have a wonderful way of describing things and I hope you understand that your efforts matter.

  • I'm thinking that lac operon is supposed to be an example of a negative control rather than positive control... Correct me if I got it wrong, that positive control has to do with activators and negative control has to do with repressors. Whether the gene is switched on or off is termed induction or repression.

  • @yang94329 I'm pretty sure you are right. A negative control is always on unless turned off by a repressor

  • @yang94329 I think you are right. lac operon in the case of this video is an example of negative control. Mr. Andersen made a mistake here. The truth is that lac operon can be used as negative and positive control because it has both a represor and an activator. The activator is cap, which is activated when it binds to cAMP, and it facilitates rna polimarase to transcribe the genes 

  • @yang94329 no you are correct I'm convinced :P

  • thank you so much for an amazing video! gene regulation makes so much sense now!! you're so awesome!! thanks so much :))))

  • I dont understand why this video has a dislike .. he explains it nicely and clearly .. aah some ppl! :S

  • @Darkcurse101

    cuz they're retarded

    i personally thought the video did an amazing job in explaning

  • @Jaesango I totally agree man.

  • @Darkcurse101 probably because it was the one person who realised mr Anderson's mistake...LAC operon is negative control

  • I like the way you explain it. Thanks for doing all these vids.

  • why do i even go to school when i can learn everything on the internet?

    Thank you, you helped a lot. :)

  • Excellent simplified description of these complicated processes. However, I do believe there was a minor error. According to my genetics professor at UCD and the textbook, the repressor protein interaction is considered a mechanism of negative control. Conversely, the cAMP-CAP complex interactions are considered a mechanism of positive control because the presence of the protein complex facilitates expression of the Lac operon.

  • Dear Mr. Anderson, you're a hottie. and an awesome speaker. thanks!

  • Hahaha, right as he snapped, my computer spontaneously shut down...

  • thanks, this help alot

  • thank you! I learned a lot :)

  • This video was amazing, ive been looking everywhere for this and couldnt understand it until now, so thanks :)

  • very helpful! :)

  • thanks :)

  • (: very good teacher

  • In this case, wouldnt the repressor be considered negative control?

  • Thank you! Mr. Anderson. You are a good teacher.

  • thanks alot :) i have been searching everywhere for this on youtube and your way of explaining this was perfect :)

  • Thank u Sir, very simple and helpful. May the Lord Jesus bless u abundantly. Thank u.

  • Best biology video I've seen (I usually watch Khan Academy)

  • You Sir are Amazing. Thank You!!

  • Lac Operon is an example of negative control. Whether it's negative or positive is dependent on the regulatory protein, and in Lac Operon's case, LacI represses the transcription. Hence it should be negative, not positive.

  • Thanks so much!!! :D

  • I love you Mr Anderson!!!

  • very helpful!! i like the process of teaching. Thanks.

  • This really helped. I'm doing NCEA Level 3 biology in New Zealand. Thank you for the help. :)

  • @ParanoiaDestroyah ahh me too :)

  • Thanks for the video! Really helps me in my study of the Organisation & Control of the eukaryotic and prokaryotic genomes...which are chapters in the Singapore-Cambridge GCE 'A' Level exam :)
