Abstract
The nuclear membrane is formed by two layers achromatic membrane and perinuclear layer. In the achromatic membrane, which is essentially protein, the submicroscopic texture is foliar; in the perinuclear layer, which is lipo-protein, the lipids are distributed probably in the form of small islets in a proteinic sheet. The relations between the fine structure of the membrane and several phenomena (disintegration and reconstitution during mitosis, formation of grooves or buds, mechanical and physiological properties) are discussed.
