Based on your understanding of gene regulation in the cell and the function of the trp operon, describe how this process would be affected if there was a mutation in the operator region so that the operator could not carry out its function.
Operons are clusters of protein-coding, or structural, genes that have a related function. The protein-coding genes share a common promoter from which RNA polymerase initiates transcription. A cis-regulatory sequence known as the operator is located between the promoter and the structural genes. The operator is the binding site for a regulatory protein that represses transcription from the promoter.
