Abstract

DNA replication, transcription and translation are essential to the student’s understanding of cellular functions, yet are typically difficult concepts to grasp. Exercises that allow students to visualize these processes using DNA models can enhance the student’s understanding. These exercises can be used as visual aids during a lecture on the processes or as a separate laboratory exercise to reinforce the material taught in lecture. Materials used are inexpensive and generally found in all classrooms. Students use Post-it-notes® to construct DNA and RNA molecules and manipulate these “molecules” in the processes of replication, transcription, and translation. Plastic petri plates are used as transfer RNA to carry Post-it-note ® amino acids. The final product is a “polypeptide chain” made of post-it-notes®.
