A lab identifies two regulatory sequences near gene GENE7: an enhancer E and a silencer S. In a reporter construct containing promoter + E + S, baseline luciferase is low. Deleting S increases baseline luciferase 6-fold, while deleting E decreases luciferase to near zero. Under stimulus U, luciferase increases 8-fold only when E is present. Which mechanism best explains the regulation observed?
