Gene Design 1 - Gene Regions
Date of this Version
Plant and Soil Sciences eLibrary (PASSeL) Lesson
Overview and Objectives - Gene Regions
This lesson describes the three gene regions and their roles in gene expression. It also discusses how the regions of a gene can be altered to obtain desired trait expression.
At the completion of this lesson, you should be able to:
- Explain why gene design is an important step in the crop genetic engineering process.
- List the three regions of a gene and explain their roles in gene expression.
- Describe the two promoters discussed (35S and PEP carboxylase) and how their expression differs.
- Describe the three Bt coding regions discussed (Cry1A(b), Cry1A(c), and Cry 9c) and how their expression differs.
- Explain how gene design could be used to deal with pest resistance to the Bt toxin.
