Ch 33: DNA Manipulation

About This Chapter

Use short video lessons to reinforce your understanding of DNA manipulation. This review can be helpful if you're currently struggling with this topic in a biology course or preparing for class, college entrance or professional certification exams.

DNA Manipulation - Chapter Summary

What are restriction enzymes? What is the bacterial transformation process? How is DNA ligase used? These are among the topics you can learn more about when you refer to the lessons in this chapter. You will have the opportunity to review the DNA replication process and the creation of recombinant DNA. These complex topics are broken down into bits of information that are easy to study and retain. Once you are finished with this chapter, you should be able to:

  • Define and explain the functions of restriction enzymes and DNA polymerase
  • Explain how ligase is used to create recombinant DNA
  • List the steps involved in PCR
  • Describe how electrophoresis works
  • Explain the role of agarose gel electrophoresis
  • Relate how bacteria is transformed

Instructors guide you through simple explanations, illustrations and examples to help simplify this complex material. Learn at your own pace and on your own schedule, as lessons are accessible from any device 24/7. Self-assessment quizzes measure the depth of your knowledge and whether you will need to continue your review of any topic in these lessons.

Restriction Enzymes: Function and Definition

1. Restriction Enzymes: Function and Definition

Restriction enzymes played a critical role in the advent of genetic engineering. In this lesson, you will learn what role restriction enzymes play in creating recombinant DNA.

How Ligase is Used to Engineer Recombinant DNA

2. How Ligase is Used to Engineer Recombinant DNA

DNA ligase makes recombinant DNA technology possible. In this lesson, you will learn how new versions of genes can be designed for experiments in novel host organisms using DNA ligase.

DNA Polymerase: Definition & Function

3. DNA Polymerase: Definition & Function

In this lesson, you will learn about the important enzyme DNA polymerase and the role it plays in the process of DNA replication. When you are through, test your understanding with a brief quiz.

PCR: Steps Involved in Polymerase Chain Reaction

4. PCR: Steps Involved in Polymerase Chain Reaction

In this lesson, you will learn about the steps required to amplify DNA during PCR. The lesson will explain the role template DNA, primers, nucleotides, Taq polymerase and PCR buffer play in the denaturation, annealing and extension steps of PCR.

What is Agarose Gel Electrophoresis?

5. What is Agarose Gel Electrophoresis?

Agarose gel electrophoresis plays a key role in genetic engineering experiments. In this lesson, you'll learn what agarose is and how electrophoresis works. You'll also discover the use of agarose in this procedure.

Bacterial Transformation: Definition, Process and Genetic Engineering of E. coli

6. Bacterial Transformation: Definition, Process and Genetic Engineering of E. coli

How can a plasmid be inserted into a bacterial cell? How can transformed bacteria carrying a recombinant plasmid be distinguished from untransformed counterparts? These questions and more will be answered in this lesson.
