Biology

A biochemist replaces the DNAâ€binding domain of theyeast Gal4 protein with the DNAâ€binding domain of the Lac repressorand finds that the engineered protein no longer regulatestranscription of the GAL genes in yeast.
A. Draw a diagram of the different functionaldomains you would expect to find in the Gal4 protein and in theengineered protein.
B. What might be done to the DNAâ€binding siterecognised by this chimeric protein to make it functional inactivating transcription of the GAL genes?
