We have been proposing and implementing various models of molecular computations based on hairpins and other secondary structures of DNA. In this short article, we introduce a computational model based on dissociation of secondary structures of DNA such as hairpins and bulges. In the model, molecular machines change their state by dissociating hairpins and bulges when they receive DNA molecules as inputs or external inputs such as lights. The model is extended to a general framework for constructing molecular systems consisting of molecular machines, including sensors, actuators and computational units, which interact with one another and compose a kind of concurrent system. We briefly describe some molecular machines, some of which we have actually implemented, including molecular memory units with hierarchical addresses, logic gates (OR and AND gates), and sensors that change their structures when receiving lights.
