Overview and Objectives - Overview of Genetic Engineering
|
This is a general description of the overall process of genetic engineering. A basic explanation of the five steps for genetically engineering a crop is provided.
The five steps are:
- Locating an organism with a specific trait and extracting its DNA.
- Isolating the desired gene that controls the trait.
- Designing a gene to express in a specific way.
- Transformation, inserting the gene into the cells of a crop plant.
- Plant breeding to create transgenic plants.
At the completion of this description, you should be able to:
- Define genetic engineering.
- List and briefly explain the five basic steps in genetic engineering.
- Identify the fundamental differences between genetically engineered crops and non-genetically engineered crops.
- Explain the limitations to traditional breeding that are overcome by genetic engineering.
- Identify the approximate length of time required to obtain a marketable transgenic crop line (complete the entire crop genetic engineering process).
