Question

Activators bind to regulatory sequences in ________ and to ________ polymerase.

Accepted Answer

Hi everyone. Let's look at our next problem, identify the regulatory protein that promotes RNA polymerase finding and stimulates the transcription process. When we look at our answer choices we have activator inhibitor repressor and inducer. Well two of these are really easy to eliminate right away and that would be Choice B inhibitor and Choice C. Repressor because as you can guess by their names, both block the transcription process. So that's not what we're looking for. But it can be a little confusing because we've got two things that stimulate the transcription process, an activator and an inducer. Well can kind of help if we think of these things in kind of groups here. An activator along with an inhibitor our regulatory proteins and they have opposite effects. Activator obviously stimulating transcription process inhibitor blocking it an inducer and repress her are both small molecules that bind to a binding site and have opposite effects on the regulation of transcription inducer helping to stimulate it repressor turning it off so that can kind of help to keep those things straight. The regulatory proteins or activators and inhibitors. Small molecules are inducers and repressors. So with that in mind we can also eliminate choice de inducer since that's a small molecule rather than the regulatory protein. So we know our correct answer is choice a activator is the regulatory protein that promotes RNA polymerase finding and stimulates the transcription process. See you in the next video
