a) The lux operon is under positive control. Based on this information, does the luxR regulator sequence make a repressor protein or an activator protein?
b) How will binding of this complex affect RNA polymerase? Remember this operon is under positive control.
c) AHL is a signal molecule that V. fisheri makes to communicate with neighboring bacterial cells. This molecule can diffuse outside of the cell and into another bacterial cell in close proximity. This type of communication between bacterial cells is known as quorum sensing. If bacterial cell density is low how will this affect the lux operon? What will happen if the density is high?
