Research of Decoder Based on Molecular Beacon DNA Computing

摘要

The decoder based on molecular beacon DNA computing is an indispensable hardware foundation of the DNA computer system. It has a direct influence on the development process of DNA computer technology. Since the rules of binary logic can also be used for switching signals in molecular converter, this paper puts forward a new implementation method of logic gates, which based on the molecular beacon calculation mode, and constructs a combinational logic circuit, 2-4 decoder. In this method, logic gates are represented by molecular beacons, signals are represented by DNA single strands, which can realize the operations of logic gates in DNA type; the connection between two logic gates according to the circuit levers can be realized by the marks of tubes. It uses including heating, elution, purification, marking and testing and some standard biological engineering technology. The construction of the molecular beacon decoder can be used for the development of DNA computer.
