diakinesis /di·a·ki·ne·sis/ (di″ah-kĭ-ne´sis) the stage of first meiotic prophase in which the nucleolus and nuclear envelope disappear and the spindle fibers form.

di·a·ki·ne·sis (d   -k-n  s s, -k-)n. The final stage of the prophase in meiosis, characterized by shortening and thickening of the paired chromosomes, formation of the spindle fibers, disappearance of the nucleolus, and degeneration of the nuclear membrane. |
diakinesis

Etymology: Gk, dia + kinesis, motion
the final stage in the first meiotic prophase in gametogenesis, in which the chromosomes achieve their maximum thickness. The chiasmata and nucleolus disappear, the nuclear membrane degenerates, and the spindle fibers form in preparation for the formation of dyads. See also diplotene, leptotene, pachytene, zygotene.
diakinesis
in cell division the stage of first meiotic prophase, in which the nucleolus and nuclear envelope disappear and the spindle fibers form.
