Abstract
AbstractROM is an indispensable part in the DNA computer system. It is used to store binary data. Based on DNA computing, the ROM developed by molecular beacon can realize the data storage in a high speed and on a large scale. And it has direct influence on the development process of DNA computer technology. This paper puts forward a new implementation method of logic gates, which based on the molecular beacon calculation mode, and realize a simple combinational logic circuit, the construction of the ROM. In this method, logic gates are represented by molecular beacons. Input signals are represented by single strands of DNA, 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. The construction of the ROM, which use the molecular beacon and based on DNA computing, will play a huge role in advancing the development of DNA computer.KeywordsMolecular beaconMolecular logic gateROM
