Different DNA Content, Chromatin Condensation, and Transcription Activity in Retina Cell Nuclei of tudied with respect to their DNA content. chromatin ultrastructure, and RNA synthesizing activity. Significant differences were found. It is concluded that transcription activity depends on the proportion of decondensed chromatin, and that both may be controlled by differential DNA replication during

Does a Compensational Mechanism Exist Among the Nucleolus Organizing Regions (NORs)? which ensures the supply with ribonucleoproteins in the cell. Reports are reviewed dealing with this subject and two original studies are presented.—The number of satellite associations, and NOR-silver staining, were studied in a human female with 13/13 Robertsonian translocation and her relatives.

Heinrich Heine,Ursula Roth,Heidemarie Vahlc mitoses of a human meningioma were compared with chromosomal normal fibroblasts of the same patient. The meningioma cells showed an increased association frequency and a higher silver content of chromosome no. 14. These results also indicate that the loss of one or even more NORs can be compensated by a higher activity of the remaining NORs.
