| Outline of Final Research Achievements |
Orthogonality is a key concept that has been broadly interpreted to mean that components or elements do not affect each other or behave independently. Previously, we have developed three artificial nucleic acids, D-aTNA, L-aTNA, SNA, composed of acyclic serinol derivatives as scaffolds. All of them can form remarkably stable homo-duplexes. While D-aTNA cross-pairs neither natural DNA (D-DNA) nor RNA (D-RNA), SNA with achiral scaffold can cross-pair with D-, L-aTNA, D-DNA, and D-RNA. In the present study, we designed a logic gate with D-aTNA that is orthogonal to D-RNA, which can be activated by D-RNA input via SNA as an interface: A seesaw gate with D-aTNA and interface SNA targeting miR21 was designed. Fluorescence could successfully be amplified by D-RNA (miR21) input that triggered D-aTNA seesaw gate via SNA.
