Summary Introduction

To determine: The properties that demonstrate that lac repressor as a protein.

Introduction: An operon is a set of genes present on the same mRNA transcript and that shares a common promoter region. The lac operon is an operon that is used for metabolism and transportation of lactose in E. coli and other bacterial species.

Summary Introduction

To determine: The evidence showing that the lac repressor indeed serves as a repressor in the operon system.

Introduction: The lac operon is used for metabolism and transportation of lactose in the cells. The lac operon is activated in the presence of lactose, and when there is no lactose, the lac operon operations are suppressed by the regulatory protein called lac repressor.
