Question

Below is a diagram that shows that when Gal4 proteins bind at the DNA sequence called "UAS" present in the upstream of the gene X, then transcription from gene X takes place at higher level. In the absence of Gal4 proteins, gene X transcript is undetectable. The gene X has its own promoter "P" downstream of the "UAS" sequence where general transcription factors "TFs" can bind P is the promoter GAL4 TFs Gal4 gene UAS Increased transcription from gene X From the information, identify what kind of response sequence "UAS" is and what kind of regulatory molecule Gal4 proteins are. Explain your answer. (1.5 point)

Explanation / Answer

Here UAS acts as driver sequence and GAL 4 acts as an inducible regulator. As GAL 4 needs to be present to induce the transcription of gene X, it is an inducer molecule. The induces needs to bind to DNA sequence i.e. UAS to drive the expression of gene X.
