Chapter 8.1, Problem 1TQ
Summary Introduction

To review:

The concept that the cell manages to transcribe genes that respond to multiple stresses where each involves a different sigma factor.

Introduction:

Information required for the synthesis of proteins is stored in DNA (deoxyribonucleic acid) strands. It acts as a genetic material in all living organisms except for some viruses where RNA (ribonucleic acid) serves as the genetic material. The first step of gene expression is transcription in which the DNA sequence is copied into RNA with the help of molecular machines.
