P{lacW} insertion within 5' flanking sequences 251bp upstream of the initiating ATG.
Embryos die around the time of cellularisation exhibiting over-condensed chromatin and a block in mitosis between prophase and the initiation of anaphase. Multiple centrosomes are visible surrounding the DNA of each cell. When embryos arrest just prior to cellularisation, disorganised elongated arrays of microtubules radiates from centrosomes in all directions but they are rarely associated with any DNA.
