GED Science: Genetic Engineering Basics
About this chapter
GED: Genetic Engineering Basics - Chapter Summary
Study for GED science exam questions by learning the definition of genetic engineering and discovering the cellular origins of DNA replication. Instructors in this chapter can also show you the processes involved in creating genetically modified organisms (GMOs) through video lessons and transcripts on the following topics:
- DNA plasmids
- Restriction enzymes
- Ligase and recombinant DNA
Whether you'd like to review basic genetic engineering topics or get an introduction to this field of study, lessons can be accessed individually in whichever order you please. Instructional material is available in the form of illustrated lesson transcripts and short, engaging videos lasting five to ten minutes each. Self-guided, multiple-choice questions are also included to help you assess your grasp of the lesson's main ideas and terminology.
GED: Genetic Engineering Basics - Chapter Objectives
Lessons in this chapter are designed to teach you about such concepts as host organisms, vectors, plasmids, recognition sequences and sticky ends so you can answer genetics questions on the GED exam's science portion. These types of life science questions make up about 40% of this section's content and are formatted as short answer, hot spot, fill-in-the-blank, matching and multiple-choice questions.
Your scores on the science portion of the test, as well as the mathematical reasoning, social science and language arts sections, will be used to determine your academic preparedness for a high school equivalency diploma, an essential component in the application process for jobs or postsecondary training programs.
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.
