6.5 Regulation of Gene Expression - Review

This review will guide you through an adaptive, research-backed study session. As you answer questions, we will actively assess your current understanding of the material. Questions will continue to be drawn until you have demonstrated mastery of each learning objective.

Reviews are graded based on completion. You will receive full credit for achieving 100% mastery or answering all questions.

Learning objectives for this review:

  • Explain how operons such as the lac operon and trp operon regulate gene expression in response to environmental changes.
  • Discuss the roles of transcription factors, enhancers, silencers, and epigenetic modifications (e.g., DNA methylation and histone acetylation).
  • Explain how precise regulation of gene expression is crucial for development, cellular function, and response to environmental stimuli.
