Certain talk about the lack Opteron, which is how we control if the enzymes that break down lack toes are made or not. Now the reason that we want to control this he's because you don't want to be making these enzymes that break down lack toes. There's no lack to its present. So normally it exists like this with this giant repressor sitting on the operator. And what a repressor does is it is going to lock transcription, which I'm an abbreviated as a T exits blocking transcription over Brockington transcription. We can't obviously do translation to make the proteins that would then help to break down the laptops. So this is what is happening when we have no lack chose present. Now, if we add some lack, chose to the system over gonna see happen is the repressive is going to leave. So without the repressor, it will just erase it away. What we're going to get is we're going to get transcription of the genes, so without repress, er equals transcription of collapses, enzyme genes. So now I want to think a couple of hypothetical situations to determine what would happen. So situation a is going to be. We have a bad, um, repressor, meaning it doesn't work, so does not bind. So if we have a repressor but can't find her, operator, what we're going to have happen is we're always going to be doing transcriptions. So always t X transcription of black toes and Zain. Jeez. So we're always going to be making the locked with enzyme genes, even if there's no watches. President. So another situation want us to think about is what happens if our operators So we have broken operator, meaning that's their oppressor Can't bind to it. Well, what's gonna happen is going to be extremely similar to what happened in situation. Hey, when we have the bad repressive, we're always gonna be transforming because we can't inhibit. If the repressor cannot find because the offer on his faulty we're always gonna be transcribing those genes. Now, the last thing I want to add is the mutation of a regulatory meaning that the repressor will not find the out So regulator G. And when trying that a regulator to you are talking about a gene that's up here, that's up street. And what this does is this gene oftentimes recruits the repressor to combine. But if this gene is faulty, we're not built to recruit that repressor. So once again, we're always going to be transcribing, even if there is no lack chose for us. So essentially the moral of the story that if you disrupt any part of this cycle, that's off regulation. So if you disrupt the repressor, the repressors ability to behind or those regulatory genes that recruit the repressor, what you're going to have happen is you're always going to be transcribing the lack jeans, even if there's no lack to its present.
