Implementation of data flow logical operations via self-assembly of DNA

Self-assembly of DNA is considered a fundamental operation in realization of molecular logic circuits. We propose a new approach to implementation of data flow logical operations based on manipulating DNA strands. In our method the logic gates, input, and output signals are represented by DNA molecules. Each logical operation is carried out as soon as the operands are ready. This technique employs standard operations of genetic engineering including radioactive labeling. To check practical utility of the method a series of genetic engineering experiments have been performed. The obtained results confirm interesting properties of the DNA-based molecular data flow logic gates. This technique may be utilized in massively parallel computers.
