摘　　要：利用DNA链置换反应分别求解二输入和三输入异或门逻辑电路.对于二输入异或门电路,将不同输入值编译成不同数量输入链,将特定数量的输入链加入反应器中,与反应器中的反应链发生链置换反应,充分反应后,通过判断检验器中绿色荧光分子明灭从而得到异或门电路的解;二输入异或门逻辑电路可以推广到三输入异或门逻辑电路.该方法具有操作简单,实验成本低,可行性高等优点.Two-input and three-input XOR gate logic circuits were solved by DNA chain replacement reaction.For two input XOR gates,different input values are compiled into different input chains.When a certain number of input chains are added to the reactor,a chain displacement reaction occurs with the reaction chain in the reactor.After a full reaction,the solution of the XOR gate circuit can be obtained by judging that the green fluorescent molecules in the detector are extinguished.Two-input XOR logic circuits can be extended to three-input exclusive or gate logic circuit.This method has the advantages of simple operation,low experimental cost and high feasibility.
