Chapter 16: Control of Gene Expression

Learning Outcomes

• Understand how regulatory proteins work and why gene control is necessary for a cell’s survival.
• Differentiate between transcriptional and post-transcriptional control of gene regulation.
• Know how RNA polymerase is linked to control of transcription.
• List the four primary kinds of structural motifs and delineate their modes of action.
• Differentiate between repressors and activators, using the lac operon as an example.
• Describe the two primary kinds of transcription factors in eukaryotes.
• Understand how eukaryotic chromosome structure is associated with gene regulation.
• Know how a primary transcript is processed to effect post-transcriptional gene control.
