Operons and Gene Regulation Explained For Beginners

[@michaelkoder2663]

Great video, but I would like to comment about the end of your video. You mention the lac operon is an example of a repressible operon but in fact it is inducible. Since the lac operon uses lactose as a source of energy, it is only activated or "induced" when glucose levels are low but lactose is present. Otherwise the pathway is always shut off. The trp operon is repressible as prokaryotes need to make tryptophan to survive. The operon is always on as a result, making tryptophan. When tryptophan becomes available, the pathway is "repressed" as continuing the operate the pathway is an inefficient use of resources and waste of energy. Your video says that the trp operon is inducible.

Oh no, I must have mixed those up at the end! Thank you for pointing that out! I hope it's okay if I pin your comment! Let me know if you don't want me to and I'll write my own correction comment instead!😇👍

I learned lot more from this video than 4 days lectures of my college❤

[@LucasLearnz]

Wow, that is fantastic! I will try to keep improving so that I can teach with greater efficiency and clarity!

[@abbystevens7717]

thank you for making a very complex concept (to me, anyways) incredibly simple and understandable

[@LucasLearnz]

So happy that I could help!😁

[@LadyQueenDV]

Great explanation, very efficient!

[@LucasLearnz]

Thank you, that means a lot!

I didn't understand this concept in my cram school cause they were explaining it in a really complex and confusing manner there. Chat GTP wasn't helping either. It was only after I saw this video, that I got really clear on this concept. ( I am in 12th btw and I was wondering if they teach this in high school in the US)

[@LucasLearnz]

Wow! That's wonderful to hear! Idk if they teach it in the US high school cause I'm from Finland🙈

Thank you for this.

[@LucasLearnz]

I'm pleased that it was helpful!

[@LucasLearnz]

Please let me know if you have any questions!

Lac operon is inducible and tryptophan operon is repressible.

[@LucasLearnz]

Yes, I made a mistake here. Thanks for pointing out!

[@meribelgoldwin]

This is incorrect.

[@LucasLearnz]

Oh no! What do you mean? I don't want to mistakenly spread misinformation🙈
