Overview

In this lesson, students explore the DNA-protein interactions in the Genetic Switch Model of the lac operon. We emphasize that knowing the names of the proteins and regions on the DNA is not important. What is really important that students develop understanding of how interactions between genes and proteins allow cells to make 'smart' decisions and respond to environmental changes.
