Ch 15: AP Biology: Genetic Mutations

About This Chapter

Watch these genetics video lessons and learn about genetic mutations, mutagens, frameshift mutations and more. These lessons are just a portion of our AP Biology course.

Genetic Mutations - Chapter Summary and Learning Objectives

The lessons in this chapter begin with an examination of how point mutations, insertions and deletions affect DNA. You'll also look at the effect of genetic mutations on protein function. Close examination is paid to missense, nonsense and silent mutations. The lessons later cover mutagens and analyze how the environment can impact mutation rates. The chapter ends with a discussion of the results of frameshift mutations. Definitions and examples of different frameshift mutations are also included in this lesson. The chapter is designed to teach you how to:

  • Explain the effect of point mutations, insertions and deletions on DNA
  • Examine how mutations can change protein function, looking at missense, nonsense and silent mutations
  • Analyze how the environment affects mutation rates
  • Understand the results of frameshift mutations
