Students construct paper recombinant plasmids to simulate the methods genetic engineers use to create modified bacteria. They learn what role enzymes, DNA and genes play in the modification of organisms. For the particular model they work on, they isolate a mammal insulin gene and combine it with a bacteria's gene sequence (plasmid DNA) for production of the protein insulin.

Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Describe gel electrophoresis
Explain molecular and reproductive cloning
Describe biotechnology uses in medicine and agriculture

Describes some biotechnology methods.

Mr. Andersen explains the concepts of genetic recombination and gene mapping. [9:43]

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

There is a lot of misinformation about what a GMO is and what foods are genetically modified. Use this unit as a review or a compelling way to engage students in the topic of GMOs using a “breakout,” an innovative science teaching and entertainment platform. This unit features 3 lessons and 8 files. Lessons are aligned to NGSS.

Understand that recombinant DNA is the combination of DNA from two different sources.

Recombinant DNA is the combination of DNA from two different sources. For example, it is possible to place a human gene into bacterial DNA. Recombinant DNA technology is useful in gene cloning and in identifying the function of a gene. Learn more about recombinant dna in this learning module produced by CK-12.
