Abstract: Recently, a new insight about applying molecular computing systems has led researchers toward designing more complicated biochemical combinational circuits. The present paper introduces the structure of a simple seesaw gate which uses DNA strand displacement method. This structure has been used by researchers to design combinational circuits. In order to investigate the application of this structure in designing and simulating the molecular combinational circuits through 'AND' and 'OR' gates, we have attempted to model such combinational circuits as adder, subtractor, and 2-bit comparator; the proposed design can lead to development of a molecular arithmetic logic unit.

Keywords: molecular computing; DNA computing; strand displacement; molecular ALU; adder; subtractor; comparator; simulation; arithmetic logic unit; seesaw-gate method; circuit design; combinational circuits.
