The incorporation of formate-C14, glycine-2-C14, adenine-4, 6-C14, and phosphate-P32 into nucleic acids.

nine labeled either with C'4 or N'5. Considerable controversy has developed as to which one of these tracer compounds gives an accurate measurement of the “relativeturnover-rate― of the nucleic acids. In order to determine the “absolute turnover rate― of the nucleic acids, it is necessary to know the specific activity of the immediate precursor of the nucleic acids. Since even the ident...

The conversion of testosterone-3-C14 to C14-estradiol-17beta by human ovarian tissue.

There is a considerable body of biological data linking testosterone and other 19-carbon steroids with the estrogens. Both ovaries and testes may, under certain circumstances, produce androgens and estrogens (14). The administration of testosterone and other androgens to human subjects leads to an increased urinary excretion of estrogenic material (5-lo), which has been identified as estrone, e...
