Learning Objectives

At the end of this lesson, you should be able to:

• Describe DNA testing methods that would be used by molecular geneticists and by plant breeders in developing transgenic cultivars that have new disease resistance genes.
• Compare PCR and quantitative PCR and describe how each plays a role in transgenic approaches to creating disease resistant crops.
• Describe how gene sequence information, antibody testing and protein testing provide valuable insights for the food safety experts who evaluate crops that express transgenes.
