Introduction

• Both prokaryotes and eukaryotes depend on the regulation of transcription for the control of gene expression.
• The proteins that control gene expression at the transcriptional level are known as transcription factors.
• The DNA transcription control elements bind to them.
• Transcription factors can be characterized as either activators or repressors depending on their function.
• Positive and negative gene regulation are two distinct forms of regulation.
• Repressors initi…
