Overall DNA path of RPo matches previously determined RPo structures.
Selected RPo structures containing a completely intact transcription bubble42,43 were superimposed with the cryo-EM RPo structure by α-carbons of the structural core module (Extended Data Table 2). The resulting superposition of the nucleic acids is shown. The nucleic acids are shown as phosphate backbone worms, color-coded as shown in the key.
