Figure 4. Dynamic reorganization of chromosomes during mitosis. (H, I) Distributions of intra-chromosomal contacts made by a 20 kb cen-proximal rDNA flanking region (highlighted in grey) with the rest of chr12 in cdc20, cdc15, cdc15 released (+40 min, +60 min), nocodazole treated (G2/M noc, cdc15 noc) and asynchronous (asyn) cells. Schematic representations of chr12 are displayed atop of the graphes. Grey lines indicate centromere position. Pink arrowheads points at the right arm anaphase loop.
