What is the role of the brain-specific enhancer in the expression of gene A?
- Binding to the Mediator and stabilizing RNA polymerase II at the promoter
- Activating Pax6 in the pancreas
- Causing gene A to be transcribed in brain cells only (correct)
- Directing Pax6 gene expression in the neural tube
Which transcription factors are required to activate Pax6 in the pancreas?
Which transcription factors are required to activate Pax6 in the pancreas?
- Meis transcription factors
- Pbx1 and Meis transcription factors (correct)

What happens if the limb enhancer cannot bind to the transcription factors of a cell type?
What happens if the limb enhancer cannot bind to the transcription factors of a cell type?
- The gene is not transcribed in any cell type (correct)
