| Outline of Final Research Achievements |
Several PCR-based molecular logic gates were constructed. The logic gate was a PCR reaction mixture containing a linear DNA template (logic gate template) coding a green fluorescent protein (GFP) and a single stranded short DNA that hybridizes with the logic gate template (pre-mixed primer). Since the logic gate templates carry recognition sequences for transcriptional and translational machinery, the amplified GFP-coding sequence is translated to GFP in a coupled cell-free transcription-translation system, wired to the logic gates as a REPORT gate, that is, the output from the PCR-based logic gate is reported by green fluorescence. In this study, some PCR-based logic gates were designed to expand the variations in the logic operation pattern. Each gates designed and constructed on the study functioned properly.
