In the following schematic diagram of a region of a mammalian genome, genes A to D (triangles) are located in between a number of insulator elements (white squares) and barrier sequences (black squares). If the cis-regulatory sequence (oval) is bound by an abundant repressor protein, which gene would you expect to be expressed at a higher rate in this cell?
