Zusammenfassung:MOST existing accounts of the mitotic cycle in animals seem to indicate that the synthesis of desoxyribonucleic acid of the chromosome takes place during prophase of mitosis, so that at the end of this stage, the desoxyribonucleic acid content is double that of the interphase nucleus and this becomes halved during anaphase 1 . Support for this view by photometric analysis has been given by Caspersson 2 and more recently by Ris 3 , who find an increase of desoxyribonucleic acid taking place during prophase.
