Data. a) Time axis and the points when measurements were taken: one in cycle 13 and eight in cycle 14A; the duration of mitosis is also indicated. b) Quantitative gene expression data at different time points. Graphs show relative protein concentration (with a range from 0 to 255 fluorescence units) plotted against position on the A-P axis (the trunk region of the embryo, from 35% to 92% A-P position is scaled to relative co-ordinates [0,1]).
