| Abstract: | The chromatin ultrastructure was studied in the centromeric region of mitotic chromosomes and in interphase nuclei of mouse cells after differential staining on C-band. A new method is suggested to study centromeric region of chromosomes treated by the Giemsa banding technique. Fibers of chromosomes appeared to be packed denser in the centromeric regions of mitotic chromosomes than in arms. The disposition of chromatin fibers in the centromeric chromocentres of interphase nuclei is the same as in the centromeric regions of mitotic chromosomes. |
