Summary Introduction

To review:

The significance of the presence of multiple promoters in a gene which are specific for different sigma factors.

Introduction:

The specific DNA (deoxyribonucleic acid) sequence to which the RNA (ribonucleic acid) polymerase binds is called the promoter site. The sigma factor helps the polymerase to find the promoter region on the gene. Transcription is a process where the information on the DNA strand is copied on the RNA strand.
