Abstract
Overview and Objectives - Gene Constructs
This lesson builds upon the gene region lesson discussing the gene construct of currently used hybrids and explaining how these combinations result in a particular gene expression.
At the completion of this lesson, you should be able to:
- List four considerations genetic engineers must keep in mind when designing genes and which gene region controls each.
- Explain the difference between input and output traits and give an example of each.
- Predict how modification of a gene will influence gene expression, specifically which protein is produced, when it is produced, and how much is produced.
- Identify the gene construct and explain the expression of Bt, Liberty resistant, and Roundup-resistant lines.
- Describe how transgene expression can cause undesired effects (yield drag).
