(A) Behavior of sister centromeres (white and red arrowheads) and the SPB (yellow) at MII in (top left and right) and (bottom left and right) mutants

The graph shows changes in the SPB-cen (D1 and D2) and SPB-SPB (D3) distances. PI, phase I; PII, phase II; PIII, phase III. Bar, 2 μm. (B) Mean distances of centromeres at phase II. More than eight pairs of centromeres were examined for each analysis. (C) Changes in spindle length at MII in the (left) and (right) mutants. Graphs show kinetics of two MII spindles in the same cell. Dotted lines in graphs show boundaries of the spindle phases. (D) Duration of the spindle phases at MII. (E) Duration of MI, MII, and the MI–MII interval. Wt, wild type. Error bars indicate standard deviation.<p><b>Copyright information:</b></p><p>Taken from "Spindle checkpoint activation at meiosis I advances anaphase II onset via meiosis-specific APC/C regulation"</p><p></p><p>The Journal of Cell Biology 2008;182(2):277-288.</p><p>Published online 28 Jul 2008</p><p>PMCID:PMC2483520.</p><p></p
