Question

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

A deletion of one of the four UASG elements upstream from the GAL1 gene.

Accepted Answer

Hello everyone here we have a question telling us an upstream activating sequence, also known as a. U. A. S. Is assist acting regulatory sequence that increases the expression of a neighboring gene by acting as a binding site for trans activators. The deletion of the U. A. S. Gene element leads to a. The trans activators bind to the target at the U. A. S. Recruiting a mediator. If the U. A. S. Is deleted then the trans activators cannot bind to the target. So A. Is incorrect. Be the trans activators bind to the target at the U. A. S. Recruiting a mediator. Yet the initiation of transcription is stopped again. If the U. A. S. Gene is deleted, the trans activators cannot bind to the target, so B. Is incorrect. See the trans activators cannot bind with A U. A. S. Element and the initiation of transcription is stopped. This is correct. Lastly we have D. The trans activators cannot bind with the U. A. S. Element yet the initiation of transcription has not stopped. This is incorrect. The transcription is stopped so D. Is incorrect. So our answer here is see the trans activators cannot bind with the U. A. S. Element and the initiation of transcription is stopped. Thank you for watching. Bye!
