Fig 9. Diagrammatic summary of factor binding and chromatin structure across the active mouse rDNA repeat (Wild Type) and after deletion of Rrn3 (Rrn3-KO) or UBF (UBF-KO).

UBF is indicated in blue, RPI in green, Rrn3 in grey/green, TTF1 in red, SL1 in yellow, CTCF in dark grey and Cohesin in light grey. The CTCF adjacent phased nucleosomes are indicated in magenta and their degree of modification indicated by the height of corresponding peaks.
