GED: Genetic Engineering Basics
About this chapter
Genetic Engineering Basics - Chapter Summary and Learning Objectives
In biology laboratories, genetic engineering has become an important tool in various kinds of research. In this chapter, you'll learn how genetic engineering works. One of the most important applications of genetic engineering is in biomedical production, so you'll look at how scientists created bacteria that produce human insulin for diabetics. You'll see how scientists were able to do this using DNA plasmids, restriction enzymes, and DNA ligase. This chapter is divided into smaller lessons, so you can learn about genetic engineering one video at a time. After completing this chapter, you should be able to:
- Explain genetic engineering's applications in science
- Understand how DNA plasmids affect bacteria
- Define the role of ligase in genetic engineering
- Identify the work of restriction enzymes
|What is Genetic Engineering? - Definition and Examples||Look at the example of insulin-producing bacteria to understand the basics of genetic engineering.|
|What is a DNA Plasmid? - Importance to Genetic Engineering||Learn about the key features of a plasmid, including the multiple cloning site, origin of replication, and selectable marker.|
|Restriction Enzymes: Function and Definition||Understand the role that restriction enzymes play in created recombinant DNA.|
|How Ligase is Used to Engineer Recombinant DNA||See how new versions of genes can be designed for experiments in host organisms using the enzyme DNA ligase.|
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.
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 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.
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.
