The nuclear wall breaks down when the spireme segments into a number of bodies called 'chromo- somes' {C,D). These bodies become arranged in a plate at the equator of a spindle halfway between the centrosomes. In the next stage—the metaphase—the chromosomes split in such a manner that each of their parts contains an approximately equal amount of chromatin {E). In the next, or anaphase stage, the chromosomes formed after splitting appear to be drawn along the spindle fibers {F) to the centrosomes. Every chromosome present at the end of the prophase sends half its chromatin to either end of the spindle. The next is a reconstruction stage, or the telophase, wherein the nuclei return to the resting condition {G). The chromatin apparently again becomes scattered through the nucleus; a new nuclear wall is formed; and the cell itself constricts between the nuclei, producing two daughter cells (Fig. 2H).
