In vitro selection of nucleoprotein enzymes
Nature Biotechnology, 2001Natural nucleic acids frequently rely on proteins for stabilization or catalytic activity. In contrast, nucleic acids selected in vitro can catalyze a wide range of reactions even in the absence of proteins. To augment selected nucleic acids with protein functionalities, we have developed a technique for the selection of protein-dependent ribozyme ...

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 ...

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 ...
