NDSU Virtual Cell Animations Project animation ‘Lac Operon’. For more information please see http://vcell.ndsu.edu/animations
The Lac Operon is an example of an inducible system of gene expression. Its default state is to be inactive. Only when the right catalyst is added to the system, in this case the sugar lactose, is the process activated, allowing the genes in question to be expressed.

Very nice
But i want to say that
Your text nad the voice timing is not matched
Plz focused on that for facilating the study. Thanku
Thanks mom
ХОРОШЕ ВІДЕО!
It was really oossmm ..it helped a lot ✨..thank you so much for making these efforts😁
awesome👍👍👍
simple and valuable. well done
Very simple and perfect explanation to the complex content
Thank you so much ! Plz can anyone help me i can't understand the case when we have a mutants of operator and mutants of gene repressor🤯🤯
Helpful 😇😇
Thank you sis it is greatly used for me.keep on
1:31 LOL
2 proteins are
β galatocydase
permese
thank u for making this wonderful vdo 😀😀😀
This helped me alot..
Hey i am from india..my sister is from this university. ..
الله يخليلنا العرب 🙂
I have this topic almost in every sem… I always watch this video… Its just awesome..! I seriously dont go through the theory.. I will just watch this video😇
Difficult Concept explained in a simple way
Best one i have ever seen
Super animation
Good video as well as good explanation
lmao youre still getting comments about the allolactose thing :/ honestly, for my course (A level bio) you just need lactose. this is a three min vid, and if you want smth more in depth and of a higher qualification a 3 min vid aint it
Brilliant
Nice video
Ligma
Who else from Andre's class is watching this? Holla at ya boy!
Well done.
Good
Who else is watching this in Mr cocco Class 2018
It cured my depression
What is 'it's ' at 2:40
The best video that teach me jst before 20 minutes of my examination
beautiful !
beauuutiiiiful
10 out of 10
life is incredible
Will the lac operon keeps on working until the medium around the E. coli bacteria is rich in lactose sugar or will it only work for a desired quantity required for the metabolic reactions currently and then stop???
1:30 Wrong. Beta gal first transformers some lactose into an isomer of lactose: alllactose which binds to the repressor molecule causing a conformation al change in its shape. The repressor cannot bind to the operator and thus RNA polymerase is free to transcribe the gene coding for lactose metabolism enzymes.
Tysssssm❤✌
The 3D picturization makes it easy to understand…Thank you so much for this 😊
too short, incomplete & insufficient
Nice explanation
A very beautiful demonstration thanks
so helpful thanks a lot! I watched it after the amebia sister video which was so helpful as well and this one explained everything more!
My there hours study done in 3 min
