Division frequency at the 1/4 and 1/2 cell positions with respect to mother cell length.

<p>(A) Data for the Δ<i>slmA</i> Δ<i>minC</i> double mutant strain (PB194); (B) Δ<i>minC</i> strain (JW1165). Cell lengths are binned at 0.25 µm intervals. Arrows point to transition regions from centrally occurring divisions to divisions at cell quarters. The lengths of the mother cells are measured just before cell division. Note that only a few cells from both strains are longer than 8 µm, limiting analysis for longer cells.
