Abstract：Based on the reaction mechanism of DNA strand displacement,by cascade reaction,the dynamic link between input signal and output signal was realized and logic circuit of multi-digit full subtractor was constructed.Then digital logic circuit of multi-digit full subtractor is transformed into the corresponding logic double-rails circuit and biochemical circuit.Finally,the circuit was simulated in the visual DSD.The results further demonstrated that multi-digit full subtractor correctly expressed the state of logic"0"and logic "1". DNA strand displacement was an effective research method for the biological logic circuit.
