GAL3 promotes GAL gene expression by:
A)binding galactose only and subsequently binding to Gal80.
B)binding ATP only,and subsequently binding to Gal80.
C)binding galactose and ATP,and subsequently binding to Gal80.
D)binding galactose and ATP,and subsequently binding to Gal1,Gal7,and Gal10.
E)binding to the Gal upstream activation sequence (UAS).

Question

Quizplus · Accepted Answer

GAL3 binds both galactose and ATP and then binds to Gal80, relieving inhibition of Gal4 and allowing it to activate the GAL genes (including Gal1, Gal7, and Gal10) by binding to the UAS.
