Complex investigations of plant and animal cells showed the nucleolus as a compartmental pulsatile system with the cycle of about one hour. Two main constitutions of the nucleolus are revealed by vital cytochemical methods: lipid-positive and lipid-negative ones. A new model of transcription is suggested. According to this model the nucleolus is a place of endoplasmic reticulum formation. The programmed endoplasmic reticulum goes out to the cytoplasm through a special channel just as the nucleolus contracts.

The results obtained testify to the dependence of the interpretation of the interphase nucleus structure on the nucleus axis orientation respective to preparation plane. Variations in arrangement of nucleolus and perinucleolar vacuole with respect to the achromatic pole and centromeric ring are demonstrated.
