Incorporation of H3-thymidine into Chloroplast Dna of Marine Algae
The chloroplasts of three genera of marine algae, Dictyota, Padina, and Bryopsis, were labeled with tritiated-thymidine for various time periods during culture in "Erd-Schreiber's" solution. Autoradiographs were prepared from both smeared and sectioned material. They revealed that almost all of the radioactivity was in the cytoplasm and associated with the chloroplasts, as detected in the overl...
متن کاملIncorporation of Tritium-labeled Thymidine and Lysine into Chromosomes of Cultured Human Leukocytes
The incorporation of thymidine-H(3) and lysine-H(3) into human leukocyte chromosomes was studied in order to determine the temporal relationships between the syntheses of chromosomal deoxyribonucleic acid and chromosomal protein. The labeled compounds were incorporated into nuclei of interphase cells. Label from both precursors became apparent over the chromosomes of dividing cells. Incorporati...

DNA replication patterns of normal human leukocyte cultures. Time sequence of DNA synthesis in relation to the H3-thymidine incorporation over the nucleolus.
IN RECENT YEARS many papers dealing with DNA synthesis in short-term cultures of human peripheral blood”6 have appeared. There has been increasing evidence that the small lymphocytes under stimulation of phytohemaglutinin1’ 9 and other substances10’2 are able to proliferate and produce mito515, but very few researchers have tried to investigate the time sequence of the DNA synthesis in the inte...
متن کاملDepressed Incorporation of Thymidine-h3 into Deoxyribonucleic Acid following Administration of 7,12-dimethylbenz(alpha)anthracene.
In the experiments to be described, it was observed that the administration of 7,12-dimethylbenz(a)anthracene (7,12-DMBA) prior to the injection of tritiumlabeled thymidine (TdRH3) considerably depresses the incorporation of tritium into rat testis, intestine, and adrenal. Recovery from the effect of 7,12-DMBA occurs in intestine within 48 hr but in testis the inhibitory action of a single dose...
