Ch 28: Genetic Engineering & Cloning

About This Chapter

Brush up on the applications, effects and ethics of cloning, genetic engineering and selective breeding. By reviewing these lessons and quizzes, you can increase your chance of success on an exam or get ready for a class discussion on this topic.

Genetic Engineering & Cloning - Chapter Summary

In this chapter, you'll review how humans have been using artificial selection in plants and animals for many years and how this practice can cause unintended genetic mutations. You'll learn about genetic engineering and inbreeding practices and their modern uses. You'll also learn about some of the hotly-debated moral questions that surround genetic engineering, including human cloning.

Some of the methods used for cloning plants and animals will be introduced. You'll also learn how DNA technology has made contributions to the medical, criminal justice and agricultural fields. After you've worked through the chapter, you'll understand:

  • How artificial selection can lead to unintended mutations
  • When inbreeding is purposefully used and why
  • How genetic engineering is used to create human insulin
  • How clones are actually all around us

The text and video lessons in this chapter use an easy-to-follow instruction style and plenty of examples to ensure that your learning experience is quick and easy. After you've completed each lesson, take the self-assessment quiz to discover how well you understood the content. If you need to go back and review just a part of a video lesson, use the video tabs in the Timeline section to jump to the information that you need.

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.

The Ethics of Genetic Engineering

4. The Ethics of Genetic Engineering

In this lesson, you're going to learn about the ethics of genetic engineering. We will review two hotly debated examples, GMO crops and 'designer' babies, and their potential benefits and dangers to society.

Practical Applications of DNA Technology

5. 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.

Methods for Cloning Plants

6. Methods for Cloning Plants

We have come a long way since the days when people used to take cuttings from adult plants to make new cloned plants of the original. Learn about making cuttings as well as new methods gardeners are using to clone plants.

Animal Cloning: Definition, Examples & Extinct Animals

7. Animal Cloning: Definition, Examples & Extinct Animals

Did you know there are clones all around us? That's something many people don't realize. So what exactly are clones? This lesson investigates cloning, types of clones, and cloning's connection to extinct animals.

What is Human Cloning? - Definition, Pros & Cons

8. What is Human Cloning? - Definition, Pros & Cons

In this lesson we'll review what cloning is. Then we'll look at the pros and cons of two types of cloning - reproductive cloning and therapeutic cloning. We'll learn some of the controversy about the use of stem cells in cloning as well as potential benefits.

Human Cloning: Ethical Issues & Legality

9. Human Cloning: Ethical Issues & Legality

This lesson is going to cover some of the legality and ethical concerns surrounding the reproductive cloning of humans. We will explore several arguments on both sides of these issues.
