Preferred peripheral position of HML and HMR.
Positions were mapped relative to the nuclear envelope in strains of GFP-tagged HML and HMR loci in WT, sir3Δ, sir4Δ, yku70Δ and esc1Δ G1 and S phase MATa cells. Data are represented in bar graphs as the percentage of spots in 3 concentric zones of equal surface. The number of cells analyzed (n) is indicated. * indicates a distribution identical to random (33% in each zone; P>0.05) in a analysis. Bar is 1 µm.
