Active learning exercises can help students understand and remember complex, three-dimensional processes. By modeling molecular processes with their bodies, students gain an appreciation for the three-dimensional nature of these processes and the physical sequence of events that constitute them. The exercises presented here focus on DNA replication and the translation of mRNA into amino acid sequences, multistep processes that require specific series of events. The exercises help students appreciate the spatial and temporal frameworks of these essential cellular functions. They can be incorporated into classes when these concepts are introduced or used as review exercises for exams.
