However, H3S10P prevalence extended along the chromosomes, with completion observed during prometaphase and remaining evident at the metaphase plate, but disappearing during anaphase and telophase (Figure 3).
The metaphase plate of chromosomes occupies the equatorial cleavage furrows at right angles to the polar cleavage furrows, [gamma]-Tubulin is concentrated in the polar regions, although some signal is distributed throughout the spindle (Fig.
The egg spindle and metaphase plate can indeed be removed by micro-manipulations.
Karyotyping showed mosaic type of TS 45, XO/46, XX in metaphase plates (Figure 2).
Eighty metaphase plates were counted and a proper plate was selected to obtain karyotype formulae.
All the chromosomes are finally aligned in the center of the spindle and attached to fibers, forming what has been termed the metaphase plate. At this point in the process metaphase is complete, and the next sequence of events is grouped under anaphase.
