Chromatin domain organization and the compartmentalized distribution of chromosomal regions are essential for packaging of deoxyribonucleic acid (DNA) in the eukaryotic nucleus as well as regulated gene expression. Nucleoli are the most prominent morphological structures of cell nuclei and nucleolar organization is coupled to cell growth. It has been shown that nuclear scaffold/matrix attachmen...

Using a system of interspecies hybrids, trihybrids, and recombinants with varying proportions of genomes from three distinct Xenopus species, we provide evidence for de novo epigenetic silencing of paternal 45 S ribosomal ribonucleic acid (rRNA) genes and their species-dependent expression dominance that escapes transcriptional inactivation after homologous recombination. The same pattern of im...

The nature of the protective substance in ribosomal ribonucleic acid and protein extracts of Salmonella has been investigated. The results of experiments in which vaccines were prepared from isogenic strains and strains with defects in lipopolysaccharide synthesis show that O antigens contaminate both ribonucleic acid and protein ribosomal extracts, and are responsible for at least part of thei...

This paper presents the updated version (Y2K) of the database of ribosomal 5S ribonucleic acids (5S rRNA) and their genes (5S rDNA), http://rose.man/poznan.pl/5SData/index.html. This edition of the database contains 1985primary structures of 5S rRNA and 5S rDNA. They include 60 archaebacterial, 470 eubacterial, 63 plastid, nine mitochondrial and 1383 eukaryotic sequences. The nucleotide sequenc...

Henney, H. (The University of Texas, Austin) and R. Storck. Nucleotide composition of ribonucleic acid from Neurospora crassa. J. Bacteriol. 85:822-826. 1963.-The nucleotide composition of total, ribosomal, and soluble ribonucleic acid (RNA) from the conidia and the hyphae of Neurospora crassa was determined. The corresponding RNA classes from the two morphological types had the same base ratio...
