In a negative inducible operon, the regulator protein is synthesised as:
A. an active activator
B. an inactive activator
C. an active repressor
D. an inactive repressor

The trp operon in e.coli regulates genes that code for enzymes required for synthesis of the repressible operon. when tryptophan is not available amino acid tryptophan. the trp operon is a in the environment, the trp repressor protein activeinactiveregulated. therefore, rna polymerase can bind to the genes to begin transcription.
