  1. A regulatory protein that binds to specific sites on DNA and stimulates transcription; involved in positive control
    Activator protein
  2. A mechanism for controlling gene expression; typically transcription is terminated after initiation but before a full length mRNA is produced
    Attenuation
  3. Small signal molecule that takes part in quorum sensing
    Autoinducer
  4. The suppression of alternative catabolic pathways by a preferred source of carbon and energy
    catabolite repression
  5. A regulatory nucleotide that participates in catabolite repression
    Cyclic Amp
  6. Proteins induced by high temperature (or certain other stresses) that protect against high temperature, especially by refolding partially denatured proteins by degrading them
    Heat shock proteins
  7. response to high temperature that includes the synthesis of heat shock proteins together with other changes in gene expression
    Heat shock response
  8. production of an enzyme in response to a signal (often the presence of the substrate of the enzyme)
    Induction
  9. a mechanism for regulating gene expression in which a repressor protein prevents transcription of genes
    negative control
  10. a mechanism for regulating gene expression in which a repressor protein prevents transcription of genes
    Negative control
  11. an RNA molecule that is not translated into protein
    Noncoding RNA
  12. one or more genes transcribed into a single RNA and under the control of a single regulatory site
    Operon
  13. a mechanism for regulating gene expression in which an activator protein functions to promote transcription of genes
    positive control
  14. a regulatory system that monitors the population level and controls gene expression based on cell denisty
    quorum sensing
  15. a nucleotide that functions as a signal rather than being incorporated into RNA or DNA
    Regulatory nucleotide
  16. a series of operons controlled as a unit
    regulon
  17. preventing the synthesis of an enzyme in response to a signal
    repression
  18. a regulatory protein that binds to specific sites on dNA and blocks transcription; involved in negative control
    repressor protein
  19. one of the members of a two component system; a protein that is phosphorylated by a sensor kinase adn then acts as a regulator, often by bindign to dna
    response regulator protein
  20. one of the members of a two-component system; a protein that phosphorylates itself in response to an external signal and then transferes teh phosphoryl group to a response regulator protein
    sensor kinase protein
  21. two component regulatory system
    signal transduction
  22. a global regulatory control is activated by amino acid starvation or energy definciency
    stringent response
  23. a regulatory system consisting of two proteins; a sensor kinase and a response regulator
    two component regulatory system
