Figure 2. Longer transcripts are more effective in establishing chromosomal domain boundaries.

Normalized Hi‐C contact maps for ΔrsaA van::promoterless rsaA and derivatives of ΔrsaA van::P_rsaA‐rsaA with transcription terminators inserted 60, 560, 1,060, or 2,060 bp from the transcription start site. Only the region of the genome containing the van locus (dashed line) is shown. Above each Hi‐C contact map is a schematic of the corresponding rsaA construct with the transcription terminator shown as a black hairpin and transcript as a wavy red line. Below each map is the corresponding directional preference plot.
