A simple and universal DNA-based platform is developed to implement the required two logic gates of a half adder (or a half subtractor) in parallel triggered by the same set of inputs. The developed half adder and half subtractor are operated with the same DNA platform in an enzyme-free system. The investigations provide a new way for the prototypical DNA-based arithmetic operations and also the development of advanced circuits.
