Extended Data Fig. 7

The RPo, RP2 and Cor–RP2 structures were superimposed and the nucleic acid backbones are shown (RPo, blue; RP2, green; Cor–RP2, magenta). The helical axes of the downstream duplex DNAs, determined using curves44, are shown as thick coloured lines. The RP2 and Cor–RP2 downstream duplexes are tilted by about 35° relative to RPo.
