Both positive and negative gene regulation involve regulatory proteins (or RNA) binding to DNA. Positive regulation involves the activation of transcription by an activator protein binding to the promoter region, while negative regulation involves the inhibition of transcription by a repressor protein binding to the promoter or operator region.
