  1. Differential Gene Expression

  2. Differential Gene Transcription • What are the major differences between prokaryotic and eukaryotic genes?

  3. Differential Gene Transcription

  4. Differential Gene Transcription

  5. Differential Gene Transcription

  6. Differential Gene Transcription

  7. Promoters • How do promoters work?

  8. Enhancer • How is an enhancer different from a promoter? • Activates use of promoter • Activates promoters on same strand • Doesn’t need to be adjacent to gene • Doesn’t need to be upstream

  9. Enhancer • How can one identify presence of an enhancer? • Why are they so important?

  10. Transcription Factors • What are the major structural domains of these molecules? • DNA-binding domain • Trans-activating domain • Protein-protein interaction domain

  11. Transcription Factors • What is MITF? Trans-activating domain Protein-protein interaction domain DNA-binding domain DNA

  12. Transcription Factors • Why is PAX6 such an important molecule?

  13. Silencers • What are silencers?

  14. Transcriptional Control • Of what value is DNA methylation? • How has this been demonstrated experimentally? • How does methylation work?

  15. Transcriptional Control • What are insulators?

  16. Transcriptional Control • How does dosage compensation influence transcription? • What are Barr bodies? • How does this relate to calico cats?

  17. RNA Processing • What is the difference between nRNA and mRNA?

  18. RNA Processing • How is differential splicing of nRNA accomplished? • What is the difference between genome and proteome?

  19. Translational Control • What are some of the factors that influence gene expression at the level of translation?

  20. Translational Control

  21. Posttranslational Regulation • What is meant by this level of regulation? • How can it occur?

  22. Controlling Gene Expression
