    • n prophase In cytology, a preparatory stage in mitotic cell-division. The prophase is characterized by a more intense staining of the chromatin, the resolution of the reticulum into a skein or spireme, the breaking up of the latter into chromosomes, the appearance of the achromatic spindle, and the disappearance of the nuclear wall. The prophase is succeeded by the metaphase.
