Consider an artificial transcription factor consisting of the DNA binding domain of the lac repressor attached to the transcription activation domain of Gal4. How would this artificial transcription factor behave in yeast cells?
a. It would repress transcription from synthetic promoters that include the lac repressor binding site
b. It would not work at all – prokaryotic DNA binding domains don’t work in eukaryotes like yeast
c. It would activate transcription from synthetic promoters that include lac repressor binding site
