In this activity, students extract DNA from their cheek cells and relate the steps in the procedure to the characteristics of cells and biological molecules. Students learn key concepts about the function of DNA during the intervals required for the extraction procedure. A second optional section develops student understanding of the fundamentals of DNA structure, function and replication; this section includes hands-on modeling of DNA replication.
