Lesson Two

How can we examine DNA?


The process for discovering biotechnology begins with a strong foundation of understanding DNA. DNA is found in all living things.

Length: 1 hour

Students will be able to:

  • Extract DNA from common fruits / vegetables.

Next Generation Science Standards Addressed:

  • Disciplinary Core Ideas:
    1. LS1.B Growth and Development of Organisms
    2. LS3.A Inheritance of Traits
    3. LS3.B Variation of Traits

  • Practices:
    Planning and Carrying Out Investigations

  • Cross-Cutting Concepts:
    Complex and microscopic structures and systems can be visualized, modeled, and used to describe how their function depends on the relationships among its parts, therefore complex natural structures / systems can be analyzed to determine how they function.
