Global Regulatory Mechanisms

The genetic code is a degenerate, non-overlapping set of 64 codons that encodes for 21 amino acids and 3 stop codons.

The trp operon is a repressor operon that is either activated or repressed based on the levels of tryptophan in the environment.

The stringent response is a stress response that occurs in bacteria in reaction to amino-acid starvation or other stress conditions.

Repression of anabolic pathways is regulated by altering transcription rates.

The L-arabinose operon, also called ara operon, encodes enzymes needed for the catabolism of arabinose to xylulose 5-phosphate.
