Mutation in the regulatory gene of a positively controlled operon can be identified by __________

Mutation in the regulatory gene of a positively controlled operon can be identified by __________ Correct Answer Operon repression

In a positively controlled operon the function of the gene is normally active thus no repressor molecules is produced that binds to the operator. Mutation in the regulatory gene leads to the production of repressor molecules that either binds to the operator or the transcription factors thus blocking the function of operon leading to operon repression.
