WebMar 6, 2024 · These techniques were the first to observe chromatin structure directly in the nucleus through electron microscopy. It was found that chromatin existed in disordered curved chains with a diameter of 5–24 nm at any stage of the cell cycle, but the concentration distribution in three-dimensional space varied with the cell stage. WebJul 25, 2024 · In interphase cells, rDNA can be found inside and adjacent to nucleoli and the location is indicative for transcriptional activity of ribosomal genes—inactive rDNA (outside) versus active one (inside). Moreover, the nucleolus itself acts as a spatial organizer of non-nucleolar chromatin.
