Gene Regulation and the Operon

[@AmoebaSisters]

UPDATE: 1. Isn't it fascinating that, as mentioned, ALL of your DNA is found in your body cells, but genes can be turned "on" or "off?" We just want to to note: there are a few body cells that do not have *any* DNA though. Mature red blood cells or cornified epidermal cells for example. Always some fascinating exceptions in biology. 2. If you're studying the lac operon, we want to remind you that our video looks at basic concepts with the goal of inspiring to explore more. For example, we don't talk about the conversion of lactose to allolactose, the cAMP-CAP conversion that stimulates the RNA polymerase, or the names of the different genes and their individual functions. We also don't mention that there are other factors that can affect the activation of this operon (such as glucose levels). Check out the further reading details to explore more! Also, did you know we have a gene regulation GIF? Find it and more of our science GIFs here www.amoebasisters.com/gifs

your videos are so helpful that I am 7th grade, and I always watch this before my test and I would get an A on my test! Thank you so much for uploading such helpful videos! You saved my grade...

[@sarahabaza9684]

thank you ,it's really helpful and fun too ..❤❤❤

Please do a tryptophan operon soon 🙏🙏🙏

[@MrNechine]

Great that you pinned this message! As this is not sufficient for biochemistry at the university I was going to comment on what you mentioned here. But otherwise, great video! It's great as an introduction to the topic.

[@private7285]

There is definitely demand for more in-depth topics for more advanced students, please make a separate playlist for advanced topics since you are so gifted with the ability to explain complex topics with simplicity 🙏

These are the best videos to help understand really complicated concepts. I am a college student and these videos are a still a huge help, especially since it takes hard to understand concepts and breaks them down without sacrificing the small important details.

There's a certain point in bio lectures where you know the definitions but just want a nice visual and put all of it together. This is the video to watch, thank you.

[@bendandsnatch2683]

"Why do we even need to learn this strand if we're never going to use it!" This has to be the greatest biology/teacher joke of all time. Also, "You are here. You must be here to synthesize HCL" is a hilarious, immediately familiar way to describe the concept. As a 26 year old "adult" college student, I mostly watch these for super dorky biology humor that motivates me to get back into the dry stuff. Thank you!!
