Free response practice

Some video links to help with your understanding of gene regulation

• Control of Gene Expression in Eukaryotes
• Processing of Gene Information: Prokaryotes vs Eukaryotes
• The lac operon
• The tryptophan repressor

Based on your work with the PHET simulation for lac operons, you should be able to answer the following free response question from the 2013 AP Biology test.  Please add your answer to your submission for the lac operon assignment before turning it in.  Remember, you are working in groups of 2 (or 3) for this assignment, everyone should equally participate in constructing your answer to the free response question.  Use this assignment as a way to discuss and practice what you will write for the free response portion of the test.
