Summary Introduction

In prokaryotic organisms, transcription is controlled by either positive or negative control. The positive and negative control is mediated by activators and repressors, respectively. Repressors are the molecules, which interfere with transcription, whereas activators induce or stimulate the transcription. Lac operon and trp operon are examples of prokaryotic regulation of transcription.
