Exam 2- Covers gene regulation to the end Test your understanding 1. What are the factors that contribute to gene regulation? 2. Differentiate constitutive expression and regulated expression and give examples 3. Explain on the turning on and off of the gene regulation *s* 4. Draw and label the system of operon which includes all of the important basic parts. Explain the importance of gene regulation *s* 5. Explain the events that you expect to happen in the regulation of lac operon. i.e. when feeding -high lactose, high glucose -high glucose, low lactose -high lactose low glucose *s* 6. Differentiate silent mutation, missense mutation, nonsense mutation (gene? Chromosome?) *s* 7. Differentiate gene mutation and chromosomal mutation*s* 8. Give examples on missense mutation, nonsense mutation *s* 9. What is dissimilar between somatic mutation and germ-line mutation *s* 10. Explain why frameshift mutation is a dire mutation than that of the point mutation All of the amino structures would be changed. 11. What are the 2 factors that contribute to mutation *s* 12. Explain on the 4 ways to repair DNA damage *s* 13. There are 2 types of chromosomal mutations, structurally and numerically. Explain all that you know on these mutations. Cri-du chat, trisomy, monosomy? *s* 14. What are the examples of polyploidy and what are the advantages *s* 15. What are the three basic ways that you know involving gene transfer? Explain each case *s* 16. Draw the genetic map of this interrupted mating technique Promoter------operator------(genes) aziS—thr+ --leu+ --gal+ --lac+ 17. What happens when: F+ meets F2F+ Hfr meets FHfr & FF’ meets FF’ + What is F’ by the way? What is Hfr and how did it occur? 18. Explain the difference between specialized transduction and generalized transduction 19. Explain the ways in transformation F+HfrF’
