title: [Chromatin fibril. Structure and relationship to the nuclear membrane].
abstract: Literature for the recent years on chromatin fibrilla structure is reviewed in the work. Ultrastructural and molecular organization of the elementary chromatin subunits--nucleosomes, discovered in 1974 is discussed and their relation to other discrete chromatin particles is analyzed. The author represents his own data on electron microscopic studies of the cell nucleus after certain experimental effect demonstrating a complex structure of chromatin particles. The scheme of chromatin fibrilla structure is given; morphologic and functional aspects of its connection with the nuclear membrane are considered.
