Some bacterial promoter regions are regulated by _______ that stimulate RNA polymerase binding and by _______ that block RNA polymerase binding.

Question

Quizplus · Accepted Answer

Bacterial promoter regions can be regulated by activators, which stimulate RNA polymerase binding, or repressors, which block RNA polymerase binding. Inducers and suppressors are specific types of activators and repressors, respectively, but not all regulators fall into these categories. Triggers and arrestors are not commonly used terms in the regulation of bacterial promoters. Promoters and operators are both DNA sequences involved in gene expression, but promoters are specifically recognized by RNA polymerase, while operators are recognized by transcription factors.
