Ch 13: Glencoe Biology Chapter 13: Genetics and Biotechnology

About This Chapter

The Genetics and Biotechnology chapter of this Glencoe Biology companion course helps students learn the essential biology lessons of genetic engineering. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Genetics and Biotechnology textbook chapter.

How it works:

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

Students will learn:

  • Artificial selection
  • Effects of inbreeding
  • Recombinant DNA
  • DNA plasmids
  • Restriction enzymes
  • DNA ligase
  • The Sanger method
  • Genomic mapping
  • Applications of DNA technology

Artificial Selection in Evolution

1. Artificial Selection in Evolution

Humans have been selectively breeding for desirable traits in plants and animals for a long time. This artificial selection allows for a lot of control in the breeding process but can also lead to unintended mutations within a population of organisms.

Inbreeding: Definition and Effects

2. Inbreeding: Definition and Effects

You know you're not supposed to marry your sister or even your cousin. But why? In this lesson, learn why inbreeding can be harmful, but on the other hand, why it's sometimes done on purpose.

What is Genetic Engineering? - Definition and Examples

3. What is Genetic Engineering? - Definition and Examples

How do we make the insulin used by diabetic patients? In this lesson, you'll learn the basics of how genetic engineering can be used to transform a bacterial host cell into a genetically-modified organism that produces human insulin.

What is a DNA Plasmid? - Importance to Genetic Engineering

4. 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

5. 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

6. 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.

The Sanger Method of DNA Sequencing

7. 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.

Genomic DNA Analysis

8. 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.

Practical Applications of DNA Technology

9. Practical Applications of DNA Technology

DNA technology is a field that has many applications for our everyday lives. In this video lesson, you will learn about some of the important contributions of DNA technology to industries such as medicine, agriculture and criminal investigation.
