diakinesis

 [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

(dī'ă-ki-nē'sis),
Final stage of prophase in meiosis I, in which the chiasmata present during the diplotene stage disappear, the chromosomes continue to shorten, and the nucleolus and nuclear membrane disappear.
[G. dia, through, + kinēsis, movement]

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.

diakinesis

(dī′ə-kə-nē′sĭs, -kī-)
n. pl. diakine·ses (-sēz)
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.

di′a·ki·net′ic (-nĕt′ĭk) adj.

diakinesis

[dī′əkinē′sis, dī′əkī-]
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.

di·a·ki·ne·sis

(dī'ă-ki-nē'sis)
Final stage of prophase in meiosis I, in which the chromosomes continue to shorten and the nucleolus and nuclear membrane disappear.
[G. dia, through, + kinēsis, movement]

diakinesis

One of the stages in the process of division of eggs and sperms which ensures that the number of CHROMOSOMES is halved (meiosis). In diakinesis the chromosomes shorten and thicken and the spindle fibres form, ready for the separation of the chromosomes.

diakinesis

the final stage in Prophase I of MEIOSIS where the chromosomes reach maximum contraction with the HOMOLOGOUS CHROMOSOMES tending to separate from each other. The NUCLEOLUS disappears, the nuclear membrane degenerates and a spindle is formed of microtubules produced by the CENTROSOMES.

diakinesis

in cell division the stage of first meiotic prophase, in which the nucleolus and nuclear envelope disappear and the spindle fibers form.
