This article presents a developmentally appropriate approach to introduce high school biology students to the structure of DNA and illustrate how its structure and function are related. We address the importance of beginning instruction with a concrete representation of DNA, and using it to scaffold to several important biological concepts. We also make clear the teacher's crucial role in this scaffolding process. This article promotes National Science Education Content Standards C and G, and Iowa Teaching Standards 1, 2, 3, 4, and 7.
