a.

Summary Introduction

To determine:

The following types of transcriptional control indicate whether the protein produced by the regulator gene will be synthesized initially as an active repressor or as an inactive repressor negative control in a repressible operon.

Introduction:

An operon is defined as a group of genes that have a common promoter and regulator and also transcribed as a single unit. This transcription results in the production of the single $\text{mRNA}$ which encodes several types of proteins. Operons are two types inducible operons and repressible operons.

Summary Introduction

To determine:

Which sequence (A, B, C, and D) is part of following components of the operon: regulator gene, promoter, structural gene for enzyme 1, and structural gene for enzyme 2.
