[The results of and prospects for the study of the interphase nucleus of eukaryotes].

Being devoted to studies in structural peculiarities of chromatin distribution of interphase nuclei from eucaryote cells, the paper embraces literature data and the authors' results in this field. Main tendencies in development of the method, based on the qualitative and quantitative estimation of hetero- and euchromatin nucleus substance are considered. Basic successes achieved while estimating experimental and clinical materials are indicated. It is determined as promising to put the method into practice.
