GAL3 encodes a transcriptional regulator in GAL gene activation, in the presence of galactose. The deletion of the entire GAL3 gene leads to?

• A. Stable GAL80 – GAL3 complex formation, enhancing the GAL gene expression
• B. GAL80 – GAL3 complex is not formed, enhancing the GAL gene expression
• C. GAL80 – GAL3 complex is not formed, inhibiting the GAL gene expression
• D. None of these

Answer: (C)
