The invention provides an implementation method of a three-cascade molecular combinational circuit based on DNA strand displacement. The implementation method comprises the following steps: researching a DNA strand displacement reaction principle based on DNA strand displacement reaction; respectively designing an AND-OR molecular combinational logic gate, an AND-NOT-OR molecular combinational logic gate and an XOR-XNOR molecular combinational logic gate according to a DNA strand displacement reaction principle; carrying out simulation verification by using Visual DSD (Digital Subscriber Device); an AND-OR molecular combinational logic gate, an AND-NOT-OR molecular combinational logic gate and an XOR-XNOR molecular combinational logic gate are sequentially cascaded to form a three-cascademolecular combinational logic circuit; and carrying out simulation analysis by using a three-cascade molecular combinational logic circuit obtained by Visual DSD software. The dynamic behavior of thecascade molecular combinational logic circuit is verified, and the reasonability of the circuit is proved; and a basic theoretical basis is provided for constructing a more complex logic operation circuit in the future, and the development of the biological computer is promoted, so that the reliability of the logic circuit of the biological computer is improved.
