The double band of chromatin has been split up into four primary chromosomes, each of these pre- serving its double nature. The achromatic spindle is now begin- ning to appear, the fibrils of the spindle converging to two poles which are at opposite ends of the cell. 6. AFiNALPROPkASE{mona8ter stage) seen in surface view. The primary chromosomes have been guided into the median equatorial plane of the spindle, so as to form a star-shaped figure. Each chromosome lies with its bend towards the centre of the median plane.
