Question

Explain how the following mutations would affect transcription of the yeast GAL1 gene in the presence of galactose.

A point mutation in the GAL1 core promoter that alters the sequence of the TATA box.

Accepted Answer

Hello, everyone and welcome to today's video. So what is their function of this AD P in the transcription of regulation of galactose metabolism in ears? As answer choice. A we have inducer B is repressor C promoter, the activator. So in order to solve this problem, we need to understand what this molecule is going to be doing in the presence or absence of galactus. So this goal ad P molecule is going to negatively regulate golf the gulf four gene that is going to make the gulf four protein. Now, in the absence of galactus, this gall ad P is going to bind to gall four and it's going to prevent transcription activation. Now, a molecule that is going to bind to a certain gene and is going to prevent transcription. A transcription activation is called a repressor. It is called a repressor because it is repressing the activation of transcription. So that is why what we're going to be using to remind us of this now because we stated that this call AD P is going to be a repressor. The correct answer for this question is B repressor. I really hope this helped and I hope to see you on the next video.
