Regulation Of Gene Transcription

Question

The transcription of five different genes is regulated by specific combinations of binding sites, as follows:

Gene 1 is regulated by binding sites A, B, and D.

Gene 2 is regulated by binding sites A, D, and F.

Gene 3 is regulated by binding sites B, C, and D.

Gene 4 is regulated by binding sites B, D, and E.

Gene 5 is regulated by binding sites A, D, and E.

If transcription factors TF-A, TF-B, TF-D, and TF-E are all active in the cell, which genes will be transcribed?
