NUCLEOPROTEIN SYNTHESIS IN THE MITOCHONDRION
Canadian Journal of Genetics and Cytology, 1969Lipolated (fat-filled) mitochondria in Saccharomyces have been observed both by light-microscopy and by electron-microscopy. Previous workers have shown, by ultraviolet-microscopy and by fat stains, using the light-microscope, that the lipolated mitochondria contain both lipids and ribonucleotides.

Extracellular truncated influenza virus nucleoprotein
Virus Research, 2001In the culture medium of MDCK cells infected with influenza A/Duck/Ukraine/1/63(H3N8) virus two kinds of virus nucleoprotein (NP) are detected: full-length 56 kDa NP and truncated 53 kDa NP. However, in infected cells 53 kDa NP may be detected only at short pulse and after 10 min chase it becomes nondetectable.

Physical properties of thymus nucleoprotein
Biochimica et Biophysica Acta, 1954Abstract 1. 1. Nucleoprotein prepared by washing with dilute salt solution and extracting with water can be obtained mainly in the form of a highly aggregated gel-like material. 2. 2. The dispersed nucleoprotein obtained by several previous investigators is probably formed by enzymic degradation of the gel-like material.

Ionic strength effects on nucleoproteins
International Journal of Biochemistry, 1978Abstract 1. 1. Homogenization of calf (Bos bovinus) thymus cells in 0.15 M triethanolamine hydrochloride (TEA-HC1) prior to the extraction of deoxyribonucleoprotein (DNP) with 0.01 M glycine results in the recovery of a fractionated DNP when compared to extracts from cells initially exposed to lower ionic strength TEA-HC1 solutions. 2. 2. The

1991
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
