Our roots reach back to the depths of the past. The grand process — at least within our view of space and time — seems to have endeavored over a period of 10–20 billion years to gain a certain consciousness and understanding of itself. Together with the universe, life patterns originated in their early infancy from an alien phase transition between ...

Dinoflagellate viral nucleoproteins
2015Dinoflagellates are an exceptional group of unicellular microorganisms that exhibit a novel perspective in chromatin biology as they bear a number of unique characteristics. Their genome sizes are the largest among eukaryotes. Despite this, the conventional nucleosomal organization in eukaryotic chromosomes are not detectable in the nucleus of ...

Expression of mammalian spermatozoal nucleoproteins
Microscopy Research and Technique, 2003AbstractA dramatic remodeling of sperm chromatin occurs during mammalian spermiogenesis. Nuclear elongation and chromatin condensation are concomitant with modifications in the basic protein complement associated with DNA. A number of biochemical events accompany the displacement of histones and the appearance of protamines in elongating spermatids ...

Enzymic degradation of thymus nucleoprotein
Biochimica et Biophysica Acta, 1963Abstract Gel-forming deoxyribonucleprotein from calf thymus was treated separately with DNAase II, trypsin and chymotrypsin. The rate of decrease in rigidity and viscosity, the solubilization of DNA and histone products, and the hydrolysis of peptide bonds were followed. 1. 1. A complete loss of rigidity was obtained either by the scission of the

Zinc in Nuclear Desoxyribose Nucleoprotein
Nature, 1949SINCE 1938 I have been engaged in a general study of the distribution of zinc in normal and malignant tissues, and this work has been briefly reported from time to time1. In the early part of the work, polarographic analyses for zinc content were made on human tissues, and although some neoplasms were found to have a much higher zinc concentration ...
