Quizplus · Accepted Answer

Global regulators control large numbers of genes in response to broad, general signals, such as environmental changes or stress. Examples include the alternative sigma factor, which switches on a large number of stress-response genes in bacteria, and the transcription factor NF-kB, which is activated in response to a wide variety of inflammatory stimuli in animals.
