Genetic Engineering Challenge – How can scientists develop a type of rice that could prevent vitamin A deficiency?

Parts of rice diagram

This analysis and discussion activity begins with an introduction to vitamin A deficiency and a review of transcription, translation, and the universal genetic code.

Several questions challenge students to design a basic plan that could produce a genetically engineered rice plant that makes rice grains that contain pro-vitamin A. Subsequent information and questions guide students as they learn how scientists use bacteria to insert desired genes, together with an appropriate promoter, in the DNA of plant cells.

In a final optional section, students evaluate the pro and con arguments in the controversy concerning Golden Rice.

The Student Handout is available in the first two attached files and as a Google doc designed for use in online instruction and distance learning. The Teacher Notes, available in the last two attached files, provide instructional suggestions and background information and explain how this activity is aligned with the Next Generation Science Standards.
