Techniques are described for the isolation of nuclei from animals cells and for the determination of the desoxyribonucleic acid content for each nucleus. These techniques have already been used in order to study a few mammalian species. From the first results (especially in calf, ox and bull), it seems to appear that the nucleus of the somatic cells contains constantly the same amount of desoxyribonucleic acid, whatever tissue and animal we studied within the same species; and this amount is…

Findings indicate that the onset of DNA synthesis is independent of a preceding cell division, a preceding nuclear division, of the average amount of DNA present, and of the main portion of RNA synthesis.

Zytophotometrische Bestimmung des DNS-Gehaltes von Zellen des lymphatischen Gewebes

SummaryThe various cell types of human tonsils have been identified and photographically documented on imprints with the Pappenheim stain. The slides were then restained with the Feulgen-method. By

Quantitative DNS-Bestimmungen von Ameisenhirnzellen

Ants which were kept in the laboratory for nearly two years did not show such a regular change in the Feulgen dye in their brain cells, and these nuclei never reached the colour intensity of those ants from a natural habitat.

Desoxyribose nucleic acid in embryonic diploid and haploid tissues

Older, more differentiated tissues were found to have a narrower range of DNA values than younger, less differentiated tissues, and the correlation of changes in this range with progressive differentiation was found to be positive.

Comparative microphotometric studies of DNA and arginine in plant nuclei

Photometric measurements have been made of the amounts of stain formed in the Feulgen (DNA) and Sakaguchi (arginine) reactions in plant nuclei of differing ploidy, suggesting that there is some degree of quantitative constancy of nuclear arginine which parallels that of DNA.

The C-value enigma in plants and animals: a review of parallels and an appeal for partnership.

The fundamental questions of the C-value enigma clearly transcend taxonomic boundaries, and increased communication is therefore urged among those who study genome size evolution, whether in plants, animals or other organisms.

Molecules and Macroevolution: A Gouldian View of the Genome

The hierarchical conception of macroevolution espoused by Gould is brought to bear on phenomena including the evolution of transposable elements within genomes and the effects of total genome size on higher level properties including at the cellular, organismal, and ecological scales.

Brains of adult Myrmica laevinodis workers were Feulgen stained and the colour intensity measured by microspectrophotometry depended on the time the brains stayed in Schiff's reagens, which means that the time of staying in Schiffs reAGens is another factor influencing the amount of measurable DNA.

Chemical composition of subcellular particles from cultured cells of human tissue

The mitochondrial fraction for all of the tissue culture cell lines contains the greatest composition of phosphatidyl ethanolamine except for the human liver and heart cells, while the lipid P/Protein N ratio of mitochondria was greater than the other subcellular fractions from tissue-culture cell lines studied.

Estimation of the diversity of transcription in early rabbit embryos

RNA from 6-day preimplantation rabbit blastocysts hybridizes with 1.8% of the nonrepeated portion of the rabbit genome. This indicates that at least the quantitative equivalent of about 60,000 unique

It is suggested that the altered distribution of P32 in the lymphoma cell, markedly increasing the concentration in the nucleus shortly after irradiation, is correlated with the inhibition of mitosis produced by the x-rays.
