Abstract Share this page

Isolated hepatic nuclei and hepatic chromatin have been analysed for their DNA, RNA, protein and phospholipid content. The protein/DNA ratio is 3 for nuclei and 1.95 for chromatin extracted from Triton X-100 treated nuclei. The phospholipids, (2.36 +/- 0.91 (S.D.) per cent of the total nuclear material), are lost during the chromatin preparation mainly during the Triton X-100 washings of the nuclei. Nevertheless, 10 per cent of the total nuclear phospholipids remain bound to the chromatin. The comparative analysis of both nuclei and chromatin shows a difference in phospholipids and fatty acid composition. Thus, the chromatin-associated phospholipid cannot be attributed simply to contaminating nuclear membrane. This is supported by the autoradiographic study of semi-thin sections of interphase nuclei from root apices of Vicia faba in which [3H] ethanolamine is clearly localized in the chromatin and nucleolar regions of the nuclei.
