Question 3 1 pts What would happen to the expression of this gene if this cell did not have any GAL4 protein and why? It would be always off because GAL4 activates transcription . it would be always on because GAL80 won't be able to bind DNA without GAL4 it would be always on because GAL4 inhibits transcription it would only be on when galactose is present Question 4 1 pts What would happen to the expression of this gene...
