Transcription factors are proteins that help turn specific genes "on" or "off" by binding to nearby DNA. Transcription factors that are activators boost a gene's transcription. Repressors decrease transcription. Groups of transcription factor binding sites called enhancers and silencers can turn a gene on/off in specific parts of the body.AP Bio Chapter 17: Protein Synthesis. DNA vs. RNA Similarities.
