The depicted region contains two genes (cI and cro) and three promoters (PR, PL, and PRM), these promoters are direct the transcription such as;
a) PR and PL are is a weak promoter and only directs efficient transcription when an activator is bound just upstream
b) PR and PL are strong, constitutive promoters, they bind RNA polymerase efficiently and direct transcription without help from an activator
c) PRM, is a weak promoter and only directs efficient transcription when an activator is bound just upstream
d) PRM are strong, constitutive promoters, they bind RNA polymerase efficiently and direct transcription without help from an activator
