    I usually don't write comments on TH-cam, but i've been watching your videos since i was a student at university, i graduated in 2020 and i still watching them now in 2023 for phD exam preparation and all i want to say is that you are a real treasure sir. Thank you for the efforts you are making to help us knowledge seekers.

    Thank you so much shomu sir😊. The way of your teaching is just fabulous. I am a student of bsc hns in zoology. And yesterday there was a viva based on lac mutation in my college.. I studied various types of materials provided by my college. But I couldn't understand even a single line. But this video made my concept so clear that I got 9 out 10 yesterday. So I am very thankful to you sir😊

      The order of dominance is P^- > O^c> I^s>I^- . So the operon will be constitutive I guess. Though I learnt it from a note, if anyone finds anything in any standard books please share.
