pro·met·a·phase

(prō-met'ă-fāz),
The stage of mitosis or meiosis in which the nuclear membrane disintegrates and the centrioles reach the poles of the cell while the chromosomes continue to contract.

In conjunction, the equilocal distribution at metaphase, the particular arrangement at prometaphase and interphase, and the condensed state throughout the cell cycle, illustrate the mode of dispersion of the distinct heterochromatic fractions in variety Pendulum in the terms defined by Schweizer and Loidl (1987).

The wrinkling revolution process is divided into five stages: (I) prophase stage, (II) prometaphase stage, (III) metaphase stage, (IV) anaphase stage, and (V) telophase stage.
In mammalian cells, H3S10P initially occurs within a subset of genes in late G2-interphase cells but subsequently spreads along the chromosomes until completion at prometaphase, after which H3S10P is still evident at the metaphase plate [17, 18].
A similar effect is typical for nocodazole-treated cells when long-term cell cycle arrest in mitotic prometaphase resulted in apoptosis [49].
These stages are prophase, prometaphase, metaphase, anaphase, and telophase.
ZNF207 (BuGZ) directly binds and stabilizes Bub3 and uses its microtubule-binding domain to enhance the loading of Bub3 to kinetochores that have assumed initial interactions with microtubules in prometaphase [48].
Mitotic Index (MI): the number of cells in mitosis (prophase + prometaphase + metaphase + anaphase + telophase) were divided by the total number of cells (interphase + mitosis) and multiplied by 100 (PIRES et al., 2001);
In prometaphase I, the poles of the QMS converge in pairs toward the spindle axis (Fig.
Prometaphase is not observed in any of the analyzed concentrations except for one 8-hour treatment, concentration of 100 [micro]g/ml and in the control cultures 3 prometaphases (Table 2).
