Operon

[@earthtonejon]

I'm a medical student without a strong background in genetics. Your explanation was far better than the explanation given by multiple medical school professors.

[@ChadbourneZitek]

Jonathan Uhl You’re a Doctor now! How do you like it? Premed here, watching this video helped me to understand lac operon too.

[@kitkat586]

I'm in the same situation. I've been using Bozeman since AP bio and now he's even being a life saver in med school!

[@jetrogutierrez1356]

Are you a doctor now

Wow, so in 10 minutes I understood something I've spent several days trying to understand... If only all lectures could be like this.

[@Prettyordying]

Do you remember any of this? Lol I feel like I won’t

[@xnairyx]

Your videos have been the lactose to my lac operon, deactivated the repressors in my brain and allowing the information to FINALLY be understood. Thank you for that.

[@1337rico]

I swear these college professors purposely make these topics way more confusing than they need to be to boost their egos. This guys explanation is 1000x better....thank you sir

[@UltimateSpinDash]

My biology teacher showed us animations for several topics (really helpful), but unfortunately not for this topic. Thanks to you, I finally understand it.

[@Bozemanscience1]

Awesome. Thanks for the comment.

[@muchpandassowow9726]

This man has saved my biology grade

[@StephenPassman]

This has been more helpful than any lecture or book for me. As a visual learner, some subjects in biology taught mostly from the text book with the occasional image, has left me with a lack of understanding, only trying to do rote memorization for passing a test instead of understanding the concepts well. The combination of professor presence with simple and effective graphics has been extremely helpful. Thank you.

I know I'm just repeating what everyone has said thus far, but seriously... thank you so much for this. All your videos have been immensely helpful.

[@ckim2092]

Even though I watched the Khan academy video, I could not understand it. But this man solved the whole problem in JUST TEN MINUTES

[@ellieneretlis9827]

lifesaver! i have a test today and had no idea what this concept was about and now it seems so simple! you'll be the person getting me through my final exams!

[@afsariayaan6815]

right now u r nothing less than an angel for me. this topic in my textbook just sucked my mind. the video is sooooooo dammnnn awesome, im at a relief now. big thanks.

[@leacafe8479]

Monsieur Bozeman, vos vidéos (qui datent déjà de plus de sept ans !) sont le meilleur compagnon de mes cours de biologie. Merci !

[@orangecaprinun]

if Bozeman science has a video about a given topic, you can bet it's the best one! Thank you so much for these videos

[@shrutichakravarty2875]

Mr. Paul Anderson.........without your videos its sort of difficult for me to understand biology... thank u so much!!U ROCK!!!!

[@nolanbronkema769]

Watched a lot of your videos in AP Biology in High school and still watch them in college to refresh! Thanks a lot!

[@carpedinoctem9662]

You. Are. Awesome. Our AP Biology teacher is on maternity leave and we have a substitute teacher who isn't exactly a people's person. Your videos are one of the reasons why I know I'm going to ace the course. I am eternally grateful.

[@yansirreaviles5036]

Another video that helped me understand a concept I was foggy on, despite the aid of several resources. Thank you so much, sir!! You are an exceptional teacher and I hope you never stop making these videos.

[@willkeener3090]

these videos might not be as exciting as vsauce or crash course but it has helped me pass ap biology. forever grateful

[@monajenks5398]

I enjoy your videos. I am now learning about Operon and was so lost in class. Now I fully understand it. I even drew the diagram that you showed during your presentation. This will be included into my notes. THANK YOU so much.

[@lauddles1563]

Gotta tell you, PROG saved me. It is pretty much the only way I can remember how operons work. Hope I can remember it for the test on monday :)

[@paulinagiezek2557]

I'm from Poland and English is not my first language, but actually I understood more while watching this film in English than at school in Polish where we have spent hours to understand this. Thank you so much! ;)

[@nafizhamid9738]

I am a bioinformatics PhD student and this was incredibly helpful and eye opening. Thanks for your wonderful teaching.

[@jackiele5019]

This is amazing. I have learnt all the factors in class but in pieces that was not able to paint any picture. Your video is so helpful in telling the whole story. Thank you!

[@stephaniebullock9157]

I spent hours trying to understand this process by reading the textbook and within 10 minutes of watching this video it all makes sense now. I am so glad I discovered your videos, hopefully will save me a lot of headache and stress during my 8 week Microbiology class.

[@stephenkopels]

This is just a great presentation….Thank you so much. I was excited about going to my Genetics class to brag about how I finally understand how a Operon works !

You made college General Genetics as easy as high school genetics. Which is a good thing! Thank you.

[@MattG08-w6k]

Thank you, Its great to have these videos to go back over after a lecture

[@TheBackbreaker]

I am studying for my medicine school entrance exam at the moment and wow - this video helped me so, so much! Within a couple of minutes I learned the different parts of a lac-operon as well as what its use. I didn't learn about it in school before and now I know everything I need about it. You saved my day! Thank you very, very much!

Mr. Anderson, I want to find you and hug the snot out of you. Other students and I have been posting your videos on our bio class Facebook page to get a grip of what we are being "taught". You make learning fun and obtaining an understanding for the information feels like a triumph. I cannot thank you enough. -that kid who sucked at bio before your videos

[@emilypopa8038]

I'm a neuroscience major and I love so many of your videos! I think you make great analogies, and are entertaining/nice to listen to. While there have been a very slight few instances where I though the analogies were a tad off in other videos, overall, I just want to compliment you and say you are absolutely awesome and a huge help. Thank you so much :)

[@telatti]

hi, med student from PROG here :D

[@LuarLucarios]

Inducer process. It's called an inducer because lac induces the operon. (Process reduces lac in the end). Vs. Repressor process. It's called a repressor because it represses the operon in the presence tryptophan. (Process creates trp in the beginning)

[@aceofspades3000]

You have no idea what you have done for me with this video. Thank you, you saved a life.

[@serinmarypr7198]

It was really helpful sir, When I was in my class when teacher was telling about lac operon I had some issues with my friends which made me so tensed and I couldn't even pay attention to the class, but now I know the concept, thanks a lot

Very useful, excellent resource for science (i.e. Biology studies, majors), and effective presentation in the breakdown of information, material, which I shamlessly cut-paste, rip and share in my own science classes. I thank you and look forward to viewing more. You easy-going camera presence, shockingly horrible but always entertaining faux-French pronunciation make the whole package enjoyable...as the French say, "Muy tres bueno mon frere mange la fettucine!"

[@axchen93]

I have passed all my classes because of you

[@gregvisioninfosoft]

Paul, I was hoping that you might be able to answer my newbie questions (my background is not biology)... In your video you mention this mechanism of DNA and how gene expressions in the DNA are effectively turned on or off. Your two examples involved the breakdown of lactose and the production of tryptophan. I will assume that this mechanism works similarly both within a human cell as it works within a bacteria... I also understand the early point you were making that the 'environment' that surrounds the DNA is not static, and that throughout various times of the day, a given cell tissue may contain excess lactose (as during hard exercise), or no lactose (as when it becomes metabolized by this described process). Question 1: Is the main purpose of this mechanism you describe for the purpose of creating a new 'cell' (in the case of the LAC operon) that will either contain the ability to metabolize lactose, versus creating a new 'cell' that will NOT include that ability. And so protracted to also include or exclude the ability to produce tryptohpan or NOT be able to produce tryptophan. And so if we equate this to computer jargon where these two functions are what we would call a two bit word where bit 0 describes the LAC function, and bit 1 describes the Tryptophan function we see that there are four distinctly different possibilities as it relates to how a new cell can be reproduced: case 1 (LAC OFF, tryptophan OFF) = 00, case 2 (Lac ON, Tryptophan OFF) = 10, case3 (Lac OFF, Tryptophan ON) = 01, and case 4 (lac ON, tryptophan ON) = 11. If this is so, does this mean that if DNA sequences were done for each of these four cases, the DNA would in fact be 'different' for each of the newly created cells? If so, then if we protract this for the many, many different functions that are encoded into gene sequences within a DNA strand - and if each being turned on or off, will manifest in 'different DNA' sequences... Then how can they say there is one generic DNA sequence for a human being? This seems contradictory to me. For if the DNA can be so dynamic, based on the cells environment at the time, it would seem there would be huge permutations of gene sequences within a living organism. And the DNA of an eyeball, would be different than the DNA of a villi in the intestines, versus the DNA of a bone, etc... I am starting to gain an appreciation for some of this science, but this type of 'high level' question, I still do not have an appreciation for what the answer is. Any insights would be greatly appreciated.
