Figure 6

Variation of PNA conductance σ with the change in standard nucleobase step parameters [113]. The Slide, Shift, and Twist parameters affect the aromatic rings' overlap on adjacent nucleobases while the Rise parameter affects the plane-to-plane distance between the nucleobases. The Roll and Tilt parameters affect both the overlap and the interbase distance simultaneously. Figure adapted from Supplementary Information in reference [53].
