Ch 20: Campbell Biology Chapter 20: DNA Tools and Biotechnology

About This Chapter

The DNA Tools and Biotechnology chapter of this Campbell Biology Companion Course helps students learn the essential lessons associated with DNA tools and biotechnology. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the DNA Tools and Biotechnology textbook chapter.

How It Works:

  • Identify the lessons in the Campbell Biology DNA Tools and Biotechnology chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the DNA tools and biotechnology topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • The Sanger DNA sequencing method
  • The process of DNA cloning
  • Features of DNA plasmids
  • The function of restriction enzymes
  • Reagents in polymerase chain reaction
  • Steps in polymerase chain reaction
  • Techniques for gene expression analysis
  • Types of DNA technologies
  • Properties and uses of embryonic and adult stem cells
  • Applications of DNA-based biotechnology

The Sanger Method of DNA Sequencing

1. The Sanger Method of DNA Sequencing

The ability to determine the DNA sequence of an individual is a powerful tool for paternity questions and criminal investigations, among other uses. This lesson will describe one laboratory method that can be used to sequence DNA.

DNA Cloning: Definition and Process

2. DNA Cloning: Definition and Process

DNA cloning is used for a variety of purposes, but how does it work? In this video lesson, you will learn about the process of cloning DNA, as well as see examples of how cloning is used in science, medicine, and consumer products.

What is a DNA Plasmid? - Importance to Genetic Engineering

3. What is a DNA Plasmid? - Importance to Genetic Engineering

DNA plasmids play an integral part in most genetic engineering experiments. In this lesson, you'll learn about key features of a plasmid, such as a multiple cloning site, an origin of replication, and a selectable marker.

Restriction Enzymes: Function and Definition

4. 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.

PCR: Reagents Used in Polymerase Chain Reaction

5. PCR: Reagents Used in Polymerase Chain Reaction

Polymerase chain reaction (PCR) is a biotechnology technique that is used to amplify pieces of DNA. In this lesson, you will learn about five ingredients necessary to perform PCR: template DNA, nucleotides, primers, buffer and Taq polymerase.

PCR: Steps Involved in Polymerase Chain Reaction

6. 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.

Techniques for Analyzing Gene Expression

7. Techniques for Analyzing Gene Expression

This lesson covers some of the most commonly used techniques to detect gene expression at the mRNA level. We will also discuss the DNA microarray technique. A brief quiz follows the lesson.

Using DNA Technology to Determine Gene Function

8. Using DNA Technology to Determine Gene Function

There are many genes in the human body. and we don't actually know what all of them do. So. how do we find out? Modern technology and research techniques have opened up new strategies for determining gene function, three of which we'll check out in depth.

Embryonic and Adult Stem Cells: Uses, Origins & Properties

9. Embryonic and Adult Stem Cells: Uses, Origins & Properties

How can we grow a brand new windpipe? Or a heart? In this lesson, we'll learn about embryonic and adult stem cells and how scientists are using them to give people a new lease on life.

Biotechnology Applications in Medicine & Genetics

10. Biotechnology Applications in Medicine & Genetics

The word DNA is most commonly associated with criminal investigations but the applications of genetics run well beyond this one field as this lesson explains. Test your knowledge by completing the quiz at the end of the lesson.
