A) regulator
B) promoter
C) operator
D) structural genes

In the prokaryotes, the working of promote region (binding of RNA polymerase) is coordinated by the operator genes, e.g. if operator genes are occupied by the represser proteins then RNA polymerase does not bind to the promoter gene and there is no transcription.You need to login to perform this action.
