Metaphase
Captions available
The idea
Metaphase is the stage where every chromosome aligns at the metaphase plate, an equatorial plane midway between the spindle's two poles, with sister chromatids still joined by cohesin.
In practice
Armies massing along one line before battle resemble metaphase, every unit aligned at a single formation.
Where people slip
Alignment at the plate does not mean the chromatids have separated — cohesin proteins hold each pair together.
