Ch 18: TExES Life Science: Genetic Mutations

About This Chapter

When studying for the TExES Life Science 7-12 teachers certification exam, be sure to include this chapter on genetic mutations to improve your understanding of the causes and effects of mutations, genetic engineering, DNA reproduction and DNA analysis.

TExES Life Science 7-12: Genetic Mutations - Chapter Summary

Complete the activities of this chapter to prepare for questions on the Texas Examination of Educator Standards (TExES) Life Science 7-12 about the causes and effects of genetic mutations. Start by watching our professional instructors in a series of short lesson videos as they explain the processes of genetic reproduction and describe the ways in which mutagens can alter this process for better or worse. After watching this series, you should have a better understanding of:

  • Penetrance and phenotypic variability of genetic disorders
  • Effects of point mutations on DNA
  • Mutagens and other environmental effects on mutation
  • Procedures of genetic engineering
  • Restriction enzymes, ligase, ethidium bromide and agarose gel electrophoresis
  • Bacterial transformation and polymerase chain reaction
  • Laboratory and natural reproductions of DNA
  • Processes of cloning
  • DNA analysis
  • Safety concerns and applications of genetic research

All of these topics are covered at length in the chapter's lessons. They can be watched online in a variety of ways, including by computer or smartphone. Make sure that you have a clear understanding of genetic mutations by taking the short quizzes that follow the video lessons.

TExES Life Science 7-12: Genetic Mutations Objectives
