Abstract: | Electron microscopy analysis of DNA organization in histone-depleted nuclei of rat spermatogonial cells was performed. It was shown that the rosette-like structures are one of the forms of the loop organization of the meiotic cell nuclear DNA. Ions of bivalent metal play an important role in stabilizing the rosette-like structures of meiotic cells. A scheme for the restructuring of the mitotic organization of nuclear DNA into the meiotic one is suggested. |
