- Sainmhíniú molecule that regulates gene expression either by binding to repressors, thus disabling them and thus allowing certain operons to work and produce the normal gene product Tagairt COM-Terminology Coordination, based on: Wikipedia > Inducer (18.11.2020)
- Nóta An activator binds to a certain site of an operon so that RNA polymerase can then bind to the DNA to begin transcription.If an operon is "inducible" this means that transcription is normally off because a repressor is normally bound to the operator site of the operon. The repressor blocks the movement of RNA polymerase down the DNA. An inducer binds to the repressor so that the repressor detaches from the operator site and RNA polymerase can proceed down the DNA to transcribe the genes
