Chapter 10, Problem 2CT

Summary Introduction

To explain: Whether the same types of gene control operate in bacterial cells and eukaryotic cells.

Concept introduction: Gene is the fundamental unit of heredity, which is composed of DNA. Each gene specifies a particular protein. For this, the genes are converted into a useful product through the process of gene expression. Gene expression involves the conversion of DNA into RNA through the process of transcription, and this RNA will be converted into proteins through the process of translation. Operons are the set of genes containing a promoter and one or more operators that help to control the transcription process. A type of operon called lac operon, which can occur in the bacteria, is used to metabolize lactose.
