Ch 9: Holt McDougal Biology Chapter 9: Frontiers of Biotechnology

About This Chapter

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

How It Works:

  • Identify the lessons in the Holt McDougal Frontiers of Biotechnology chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the 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 behavior of restriction enzymes
  • The process of polymerase chain reaction (PCR)
  • The basics of how to clone DNA
  • Methods for sequencing DNA
  • What genomics is
  • Research models for studying genes
  • Advantages and disadvantages of gene therapy

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.

What is Agarose Gel Electrophoresis?

2. 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.

PCR: Reagents Used in Polymerase Chain Reaction

3. 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

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.

The Sanger Method of DNA Sequencing

5. 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

6. 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.

Genomic DNA Analysis

7. Genomic DNA Analysis

Your genes are what make you who you are, but they also make you a human. Studying genes and genomes allows scientists to better understand not only our own species, but how we are related to other species in the world as well.

Tools Used to Study Genes

8. Tools Used to Study Genes

For thousands of years, humans have manipulated genes to domesticate plants and animals and create new species. In this lesson, we'll learn about various indirect ways to study genes and the most recent method of direct manipulation of genes.

Human Genetics Research Methods: Pedigrees and Population Genetics

9. Human Genetics Research Methods: Pedigrees and Population Genetics

Have you ever wondered how people study human genetics? Do you know what a pedigree or a complex disease is? In this lesson you'll learn about some of the techniques that human geneticists use and what pedigrees and complex diseases have to do with human genetics.

What is Gene Therapy? - Definition, History Pros, Cons & Examples

10. What is Gene Therapy? - Definition, History Pros, Cons & Examples

Learn how gene therapy is used to treat disease, the history of the treatment and its trials, as well as the pros and cons associated with this controversial new technique.
