Which of the following mechanisms is (are) used to coordinate the expression of multiple, related genes in eukaryotic cells?
A) Environmental signals enter the cell and bind directly to promoters. B) The genes share a single common enhancer, which allows appropriate activators to turn on their transcription at the same time.
