  20. B

  21. Which of the following is a point mutation? • Inversion • Substitution • Duplication • All are point mutations

  22. B

  23. Gene regulation in eukaryotes • Is simpler than in prokaryotes • Usually involves operons • Includes the action of DNA polymerase • Allows for cell specialization

  24. D

  25. What are genes? • Chemical factors • The instructions for making proteins • Portions of the DNA • All of the above
