Representative snapshot of RNAC positions on a gene during transcription for an isolated gene torsionally constrained in one direction (composition details in SM). Spacing between RNACs is determined through random initiation, SC dependent velocities and hard core repulsion. Consequentially, as RNACs move along a gene during transcription stalling and clustering occur leading to bursts of mRNA production (Figure 3).
