The transfer of charges through double helical DNA is a very well investigated bioelectric phenomenon. RNA, on the contrary, has been less studied in this regard. The few available data report on charge transfer through RNA duplex structures mainly composed of homonucleotide sequences. In the light of the RNA world scenarios, it is an interesting question, if charge transfer can be coupled with RNA function. Functional RNAs however, contain versatile structural motifs. Therefore, electron transport also through non‐Watson–Crick base‐paired regions might be required. We here demonstrate distance‐dependent reductive charge transfer through RNA duplexes and through the non‐Watson–Crick base‐paired region of an RNA aptamer.
