Follow the link above to start or download this activity.

This Activity Requires:

  • Java 1.5+ - Java 1.5+ is available for Windows, Linux, and Mac OS X 10.4 and greater. If you are using Mac OS X 10.3, you can download MW Version 1.3 and explore within it instead.

      Test your system to see if it meets the requirements

Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page.

Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.

Overview and Learning Objectives

In this activity students design proteins that will perform several fairly simple functions, e.g., trap and carry an ion. They experiment with code for DNA that will translate into proteins with particular characteristics.

Students will be able to:

  • experiment with code for DNA that translate into proteins;
  • specify how coding of protein relates to desired protein sequence;
  • demonstrate how the distribution of charge in a protein is critical to its shape and function.
