Figure 5. Mmi1- and RNAi-mediated silencing of pericentromeric DNA transcription alternate during the progression of the cell cycle. (B) ChIPs showing the localization of Mmi1 (dashed line) and H3K9me2 (black line) to the pericentromeric nam5/6/7 DNA regions during the progression of the cell cycle. Cell synchronization was achieved by using cdc25-ts cells (see experimental procedures for more details). Cell synchronization was monitored by measuring the percentage of cells with a septum (right part).
