Thank you, soo much for your effort and time making this videos. Such a big help to all student around the world. I just can't thank you enough. Almost gave up on studying biochemistry but your video change that. easy, simple, direct and informative lecture ever! Yeah, best lecturer ever. You should get tons of awards for all this.
I know this takes so much time and effort, but you are truly a lifesaver. I'm taking biochem at UGA with about 300 other students and I would honestly be failing without your lectures. You are like superman, saving each science major student one at a time!! Seriously you are awesome.
I never understood this in university. Always gave me an annoying headache but this video changed everything. You are truly gifted. Thank you for what you are doing. You are simply amazing!!
Your lectures are the reason that I am getting an A in Gen Biochm 1 !!! Thank you very much for your time and dedication for doing these review lectures!
Signed in just to give you a thumbs up. What i really like about your lectures is the way you build up the concept/purpose of what is being discussed. Great job.
Andrey you are such a gifted lecturer! I've had the operon discussed in countless courses but never really understood it until now WOW! Thank you so much for all your hard work, it is truly appreciated!
Oh lord, Mr. AK The Best, you are my A's in microbio! Thank you, please remain as amazing as you are and keep getting only better and better as you have been!
you really are something else andrey thank you so so much for everything you’ve helped me expand my knowledge not only in school but in life in general - life is even more beautiful and colorful now
Really wish I knew about your lectures earlier. SOOO clear and easy to understand. Love having the notes already written out helps me set up my own notes and know what's coming. THANK YOU ENDLESSLY
I always hope to find your videos when trying to learn biology. The book gives me the information but these videos allow me to actually learn the material. You're clear, well-paced and I love the little diagrams. Thank you for all your help!
man, i'm a first year dental student, swear to god.... your lectures helped me with every single class... from genetics to embryology, biochemistry, chemistry... many many classes... sir i'm beyond thankful like srsly you are the best thank god for your existence god bless you for real
I really don't know what to say to thank you. .You You help me a lot .because of you I start being bossed to genetic ..You do great effortSo keep it up .My Allah guide you
thanku thanku thanku.....sir I am doing fsc through federal board in pakistan....and our badge is the only badge who got biology book of NBF and this topic is also included in our book....and it is not present in any other book of grade 12.... thank god u taught me.....My prayers are with u....
ahh...im loving all ur videos! we have whole biochemistryyy heree!!!! plzz keep uploadingggg.....ur videos r giving me hope to crack my entrances... thankuu soo muchh
in the coding region there is three genes one is called Beta-galactosidase that break lactose into glucose and galactose,permease that permit enter the lactose into the cell while transacetylase to detoxify non-metabolizable pyranosides by acetylating them and preventing their reentry into the cell
Correction: RNA polymerase binds to the promotor on the regulatory gene and transcribes the repressor protein which will bind to the operator on the operon. (Sourced from a Campbell CH27)
Thank you soo MUCH sir.your way of teaching is fantabulous I have a question that How cAMP is attached to CAP. While in your diagram I understand that CAP is attached to CAP site but where cAMP is attached to CAP ??and what is the reason of increase of cAMP when there is low concentration of glucose?. I like your lectures alot ,are easy simple, and enlightening .
Thank you so much for this explanation and all that you do. 👏👏 I would like to ask what the relationship is between reduced glucose concentration and cyclic AMP
you are a beast! thank you for all your videos. tiny confusion for me... for site 3, is that what the texbook refers to as enhancers? i thought they can be really far away(upto 1000 base pairs? but here they are next to promotor?) it also said it aids in the transcription of the structural genes but is it essential ( as in without the enhancers, transcription would not proceed?) or is it all just a simultaneous process (site 3 binds enhancers+activators, allolactose binds repressor, promotor binds RNA Pol) and transcription happens? i guess im most confused about where site 3 is located becasue the transcriptional factors can pick up on enhancers from very far away or is it becasue of the "hairpin" like structure that makes it possible for the enhancer activators to be picked up by transcriptional factors, or are these actativators different from enhancer activators?
saw the eukaryotic regulation video and cleared up a lot of the confusion, i was mixing up prokaryotic simple gene regulation with eukaryotic gene regulation -.-
Thank you master. On minute 8 + 50 sec you said that RNA pol binds to promoter region #1 on the lac operon. I do not think that region #1 & #2 are part of the Operon. Great video anyway!
Hey there, I had a question: you mentioned that the RNA polymerase will transcribe the gene for the repressor protein. This will prevent the transcription from taking place. However, once the allolactose molecules bind to repressor protein and detach it from the operon, this would mean that the RNA polymerase can transcribe. This is where I got confused; it states in the video that the first gene in the coding section leads to the production of B-Galactotidase. Wouldn't that prevent transcription though? Isn't this the same thing as the repressor protein? If you could take the time out of your day to answer this, I'd highly appreciate it. You're a really effective teacher lol. Thank you.
love your videos but the captions are not correct! for some reason it is auto-translating to vietnamese instead of english and this makes it really hard to understand what you are saying
@@AKLECTURES I really love your teaching ... Before I never use to refer to videos without animation and now I recommend my friends your channel... (but if you ever switch to any social media accounts please let me know, adding productive people in list is a lot better then following ....) Thank you
