Ch 40: General Science: Genetic Engineering

About This Chapter

The AEPA General Science exam is now a National Evaluation Series (NES) test. The lesson and quizzes in this study guide will help you prepare for the NES General Science exam's questions on genetic engineering.

AEPA General Science: Genetic Engineering - Chapter Summary

This chapter on genetic engineering is designed to get you ready for questions on the AEPA General Science exam. Lesson topics include the function of restriction enzymes, the Sanger Method of DNA sequencing and the use of ligase to engineer recombinant DNA. Other lessons will cover:

  • Definition and examples of genetic engineering
  • Importance of DNA plasmids in genetic engineering
  • Agarose gel electrophoresis
  • Ethidium bromide, loading buffers and the DNA ladder
  • Bacterial transformation
  • Reagents and steps in polymerase chain reactions

Use these informative video lessons to catch up on topics you may not have covered in awhile or to fill in knowledge gaps. The lessons can be viewed as many times as you like until you feel you've mastered the topics. Test your understanding with self-assessment quizzes and the chapter exam.

AEPA General Science: Genetic Engineering Chapter Objectives

The lessons and quizzes in this study guide will get you ready for questions in the life science portion of the test. This test section accounts for about 25% of the total score. Among other topics, you will be asked about methods of genetic engineering and the applications of the process.

The AEPA General Science exam has 150 multiple-choice questions and is administered electronically. You will need to pass the exam if you want to become a science teacher in the state of Arizona.

What is Genetic Engineering? - Definition and Examples

1. 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

2. 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

3. 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

4. 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.

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.

Ethidium Bromide, Loading Buffer & DNA Ladder: Visualizing DNA and Determining its Size

6. Ethidium Bromide, Loading Buffer & DNA Ladder: Visualizing DNA and Determining its Size

In this lesson, you will learn about the role that ethidium bromide, loading buffers, and DNA ladders play in visualizing DNA and determining the size of DNA fragments in agarose gel electrophoresis.

Agarose Gel Electrophoresis: Equipment & Procedure

7. Agarose Gel Electrophoresis: Equipment & Procedure

This lesson will review the concepts and mechanisms of agarose gel electrophoresis. It will also summarize the equipment needed to perform the procedure for DNA analysis.

Agarose Gel Electrophoresis: Results Analysis

8. Agarose Gel Electrophoresis: Results Analysis

Gel electrophoresis is used to analyze DNA restriction digest and ligation experiments. In this lesson, you will learn how to use a DNA ladder to interpret experimental results.

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

9. 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.

Bacterial Transformation: Antibiotic Selection and Positive & Negative Controls

10. Bacterial Transformation: Antibiotic Selection and Positive & Negative Controls

The use of antibiotic selection and positive and negative controls are important elements of interpreting data from a bacterial transformation. In this lesson, you will learn how antibiotic selection results in colony formation and how controls help pinpoint the cause of experimental problems.

PCR: Reagents Used in Polymerase Chain Reaction

11. 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

12. 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

13. 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.
