Which of the following statements is accurate regarding the yeast GAL gene regulation? A) The structural genes GAL1, GAL7, and GAL10 are regulated as a polycistronic transcription unit. B) The GAL4 regulatory protein does not bind to the UAS element in the presence of galactose. C) The GAL4 regulatory protein is a repressor. D) The regulation of the GAL1 gene is repressible. E) None of these

They are transcribed separately but are coordinately regulated. B) The GAL4 regulatory protein binds to the UAS element in the presence of galactose. When galactose is present, the GAL80 repressor is removed from GAL4, allowing it to bind to the UAS element and Show more…

Which of the following is FALSE about bacterial gene expression regulation? a) Bacteria regulate gene expression mostly at the transcriptional level. b) Genes coding for proteins that work together are normally regulated together in so-called operons. c) They do not express all their genes at all times, and that's why all bacterial cells are not identical. d) Bacteria can actively turn the expression of their genes ON or OFF.
