Accepted Answer

Hi everyone. Our next question says which of the following does not describe a regular. So let's look through our answer choices here, remembering that we're looking for a false answer. One that is not the definition of a regular choice A says it is a set of operations. That is true. That is what a regular on is composed of Choice B says it's triggered by one type of regulatory protein that's also true regulatory protein interacts with that too. Um cause the regular in to have um whatever effects it's going to have on the genes that it controls. So Choice B not a correct answer. Choice C says it prevents transcription when the operator binds with an inhibitor. Yes, that is true. It's part of its action. So not our answer. So finally, we're down to Choice D. Which says it prevents an alternative site. Sorry, provides an alternative site for regulatory protein binding. Well, this is not the description of a regular this is a list eric regulation. And Alistair regulation we might recall is when you have same enzyme that has its active site here and then has this distance separate site. So the binding of the regulator to this distance site causes a change. So let's imagine our little Alice Terek regulator there causes a change when it's bound in the active site. So now let's say our substrate can no longer bind. So it doesn't interact with the active site itself. It's in a distant site having the effect on the active site. So that's a list eric regulation not a regular john So Choice D. Is our correct answer, which the following does not describe. A regular Choice D. Provides an alternative site for regulatory binding. See you in the next video.
