Chapter 7, Problem 5RQ
Summary Introduction

The lac operon is used to synthesize the β-galactosidase to metabolize the lactose in E. coli. The glucose molecule is the preferable energy source for the E.coli. The catabolic repression of the lac operon results in the synthesis of mRNA that codes for the enzymes of glucose catabolism.
