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 Sanger Method of DNA sequencing uses dideoxynucleotides to determine DNA sequencing. Explore the dideoxynucleotide structure, chain terminators, and how to interpret Sanger sequencing in this lesson.

DNA Cloning: Definition and Process

2. DNA Cloning: Definition and Process

DNA cloning is when identical copies of DNA fragments are made. Understand the definition and process of DNA cloning and explore other cloning vectors.

What is a DNA Plasmid? - Importance to Genetic Engineering

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

DNA plasmid is a vital component of genetic engineering. Learn about DNA plasmids and the three characteristics, including multiple cloning sites, replication origin, and selectable markers, that make DNA plasmids so important in genetic engineering.

Restriction Enzymes: Function and Definition

4. Restriction Enzymes: Function and Definition

Understand how restriction enzymes function. Learn about genetic engineering, the definition of a restriction enzyme, the recognition sequence, the palindromic sequence, and the sticky ends of single-strand DNA.

PCR: Reagents Used in Polymerase Chain Reaction

5. PCR: Reagents Used in Polymerase Chain Reaction

Polymerase chain reaction (PCR) is a procedure that creates copies of DNA using reagents. DNA is amplified, and the amplified DNA regions are identified by other DNA pieces using reagents, such as template DNA and PCR primers, and other key parts of DNA, including nucleotides and tag polymerases. Learn about that process, including the different elements that makes conditions optimal for PCR to occur.

PCR: Steps Involved in Polymerase Chain Reaction

6. PCR: Steps Involved in Polymerase Chain Reaction

Polymerase chain reaction (PCR) is a laboratory procedure that can create replicas of DNA. Explore the three steps of this revolutionary process: denaturation, annealing, and extension.

Techniques for Analyzing Gene Expression

7. Techniques for Analyzing Gene Expression

Gene expression initiates gene regulation which allows DNA to be turned on and relay instructions to the cell so that it knows what to do next. Study the techniques for analyzing gene expression, including mRNA detection and DNA detection.

Using DNA Technology to Determine Gene Function

8. Using DNA Technology to Determine Gene Function

The human body is comprised of thousands of genes that have a variety of purposes, such as determining an individual's eye color. Learn about using DNA technology to determine gene functions such as in-vitro mutagenesis, RNA interference, and genome-wide association studies.

Embryonic and Adult Stem Cells: Uses, Origins & Properties

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

Stem cells are unspecified cells with the potential to differentiate into specific cell types. Discover what stem cells are, learn the difference between embryonic and adult stem cells, and explore how scientists use them to save lives.

Biotechnology Applications in Medicine & Genetics

10. Biotechnology Applications in Medicine & Genetics

DNA and genetics have practical uses in many fields. Learn about biotechnology applications in medicine and genetics. Review forensics and profiling, genetics and medicine, and agriculture and the environment to understand that DNA can be beneficial in a variety of ways.
