Distribution of Mitotic Cells in Δswi6 and Δbub1 Strains

Strain		Background		Number of cells analyzed		Cells in prophase and prometaphase*		Cells in metaphase‡		Cells in anaphase and telophase§
77		Wild-type		3,583		69 (1.9%)		62 (1.7%)		312 (8.7%)
423		Δswi6::his1 +		3,090		42 (1.4%)		115 (3.7%)		322 (10.4%)
393		Δbub1::ura4 +		3,047		46 (1.5%)		67 (2.2%)		305 (10%)

^* Prophase and prometaphase were defined as cells with a spindle length shorter than 2 μm.  

^‡ Metaphase cells were defined as cells with unsegregated DNA and a spindle length greater than 2 μm and shorter than 5 μm.  

^§ Anaphase and telophase cells were defined as cells with segregated DNA and spindle length greater than 5 μm. Parentheses, fraction of each cell population.
