<span>1.
</span>They act as activators of transcription. This is

<span>2.
</span>They could act as repressors. This way, when

repress the binding of the RNA polymerase on the promoter
<span>3.
</span> Transcription factors at one site could affect transcription of genes on another site on the
DNA. The flexibility of the DNA (by forming loops) allows for this phenomenon.
