Ch 25: AP Biology: Basic Molecular Biology Laboratory Techniques

About This Chapter

Watch basic molecular biology video lessons and learn about important laboratory techniques, genetic engineering, DNA sequencing and more. These lessons are just a portion of our AP Biology course.

Basic Molecular Biology Laboratory Techniques - Chapter Summary and Learning Objectives

The lessons in this chapter begin with a definition of genetic engineering. You then can learn about DNA plasmid and its relation to genetic engineering. You'll also study more advanced topics like the functions of restriction enzymes and ligase. Lessons cover the process of agarose gel electrophoresis and how to analyze its results. You'll also be introduced to the processes of bacterial transformation and polymerase chain reactions. The chapter closes with an examination of the Sanger method of DNA sequencing. After completing this chapter, you should be able to:

  • Understand genetic engineering
  • Identify the function of restriction enzymes
  • Explain the procedure of agarose gel electrophoresis
  • Define the process of bacterial transformation
  • Name the steps and products used in a polymerase chain reaction
  • Analyze the Sanger method of DNA sequencing
