The Design of a Reverse Code Circuit Based on Deoxyribonucleic Acid Strand Displacement Reaction

In recent years, Deoxyribonucleic acid (DNA) strand displacement technology has become an integral part of DNA computing. It is well known that the reverse code logical circuit plays an important role in computer circuits. Displacement of DNA strands is an effective method for logic computation, which can achieve dynamic linking between internal input and output. The aim is to demonstrate how the logical circuit model of the reverse code circuit is designed and translated into the homologous seesaw circuit. The reaction process of DNA strand displacement is simulated in the specialized Visual DNA Strand Displacement (DSD) software. A four-bit reverse code logical circuit based on DNA strand displacement is designed through the software Visual DSD to compile and simulate the circuit. Through the analysis of the simulation results, it is indicated that the design on the basis of DNA strand displacement by dual-rail circuits is reliable. The analysis also shows that DNA strand displacement has a bright future in the construction of large-scale logical circuits due to its high programmability and versatility.
