  • Using genetic modification in nutrition
  • Microarrays
  • Gene therapy
  • Stem cell research
  • Ethics, safety issues and practical applications of DNA technology

This study guide is designed to place all of the resources you need within easy access. The lesson videos are short, yet deliver comprehensive information. Transcripts are provided with key terminology highlighted for easy referral, and you have ready access to our subject matter specialists and expert instructors whenever you need additional assistance.

Keystone Biology Exam: DNA Technology & Genomics Chapter Objectives

There are two modules that comprise the Keystone Biology exam, an end-of-course assessment test. These are Module A: Cells and Cell Processes, and Module B: Continuity and Unity of Life. The lessons in this chapter address material tested in Module B.

The Keystone Biology exam has a total of 72 questions, and may be taken either online or on paper. Each module has 32 multiple-choice questions and 4 constructed-response questions, which will require a written answer.

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.

Genomic DNA Analysis

2. 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.

DNA Sequencing and the Human Genome

3. DNA Sequencing and the Human Genome

DNA sequencing allows us to determine the exact genes that make up an individual. It can be used to screen for certain diseases and in crime scene analysis. Learn more about it in this lesson.

GMOs: Improving Nutrition and Golden Rice

4. GMOs: Improving Nutrition and Golden Rice

Golden rice is a genetically modified rice crop that produces vitamin A. In this lesson, you will learn about how golden rice is made and how it can be used to prevent blindness and death in the developing world.

Microarrays: Definition & Analyzing Genes on a Chip

5. Microarrays: Definition & Analyzing Genes on a Chip

DNA microarrays are used to quickly and efficiently measure the gene expression levels of many genes at the same time. In this lesson, you will learn how microarrays are produced and used by scientists to help identify and treat diseases.

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

6. 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.

Embryonic and Adult Stem Cells: Uses, Origins & Properties

7. Embryonic and Adult Stem Cells: Uses, Origins & Properties

How can we grow a brand new windpipe? Or a heart? In this lesson, we'll learn about embryonic and adult stem cells and how scientists are using them to give people a new lease on life.

Practical Applications of DNA Technology

8. 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.

Ethical and Safety Concerns for DNA Technology

9. Ethical and Safety Concerns for DNA Technology

DNA technology is very powerful and has had positive influences on many fields and industries. However, DNA technology is not perfect. In this lesson, you will explore some of the safety and ethical concerns that people have regarding this field of study.
