Molecular logic computing model based on DNA self-assembly strand branch migration

In this study, the DNA logic computing model is established based on the methods of DNA self-assembly and strand branch migration. By adding the signal strands, the preprogrammed signals are released with the disintegrating of initial assembly structures. Then, the computing results are able to be detected by gel electrophoresis. The whole process is controlled automatically and parallely, even triggered by the mixture of input signals. In addition, the conception of single polar and bipolar is introduced into system designing, which leads to synchronization and modularization. Recognizing the specific signal DNA strands, the computing model gives all correct results by gel experiment.
