Mechanism and regulation of ribosomal RNA transcription
The sole responsibility of RNA polymerase I (pol I) is the transcription of the ribosomal RNA (rRNA) genes. This transcription can account for up to 60% of the total cellular RNA that is being transcribed in an actively dividing cell. Due to the large amounts of energy this transcription requires, …

Minor form of human 5.8s ribosomal RNA
Part One: The Minor Form of Human 5.8S rRNA An elongated form of 5.8S rRNA has been found in a wide range of eukaryotes from yeast to rodents. This minor form of 5.8S rRNA is about six nucleotides longer than the major form and composes from 10% to 30% of the total 5.8S rRNA found in yeast and …

Evolutionary Measurements Using Ribosomal Rna Sequence Comparisons (Phylogeny)
Comparisons of complete 16S ribosomal RNA sequences have been used to confirm and refine the phylogeny of bacteria. Two bacterial 16S rRNAs have been analysed in this study.

Models for the formation of 5.8S ribosomal RNA dimer
Ribosomal 5.85 RNA is a component of the large (605) ribosomal subunit in eucaryotes. Studies of 5.85 rRNA in solution have shown that under certain conditions, including standard isolation procedures, the molecule complexes with itself to form dimers and higher multimers. Two models have been …

Stressed Induced Changes in <i>Karenia brevis</i> Ribosomal RNA
… have noted a distinct shift in the size of both ribosomal RNAs upon culturing cells under “stress” conditions, namely nutritional stress, cold shock, and decreased salinity. When the total RNA is extracted we have detected aberrant rRNA bands on the microcapillary electrophoresis BioAnalyzer …

Identifying individual ribosomal RNA gene repeats to investigate their behaviour
Ribosomal RNA forms the major structural and catalytic components of ribosomes. In eukaryotes, the ribosomal RNA genes (rDNA) are present as multiple tandem repeats that are transcribed by a dedicated polymerase, RNA polymerase I. While hundreds of rDNA repeats are present, only a subset is …

Investigation of a ribosomal RNA operon of Frankia sp. strain AcN14a.
… we have investigated the structure of the ribosomal RNA genes from Frankia sp. strain AcN14a. A genomic library was constructed in EMBL3 and two types of clones, each containing a different set of rRNA genes, were identified by restriction analysis. The rRNA genes of Frankia AcN14a have …

Identification and characterization of the ribosomal RNA operons from Rhodobacter sphaeroides
The three ribosomal RNA operons present in the facultative photoheterotroph Rhodobacter sphaeroides were identified, cloned and sequenced. DNA sequence analysis has identified the 16S, 23S and 5S rRNAs, two tRNAs (ile and ala) in the 16S-23S spacer region, and an f-met tRNA immediately following …

NMR application and development : study of the ribosomal RNA-L11 complex
The L11 protein of the large ribosomal subunit binds to a highly conserved domain of the 23S rRNA and jointly with RNA mediates GTPase activity of elongation and release factors. It consists of a C-terminal domain, which is the main anchor and determinant for the binding to rRNA and an N-terminal …

Tetrapod phylogeny as inferred from 18S and 28S ribosomal-RNA sequence comparisons
The superclass Tetrapoda consists of several well defined monophyletic taxa: Anura, Urodela, Gymnophiona, Testudinata, Squamata, Rhychocephalia, Crocodilia, Aves and Mammalia. The relationships among these groups, however, is controversial. Neither paleontological evidence nor morphological, …

Effects of retinoic acid on ribosomal RNA gene expression during limb regeneration
Genomic DNA and total RNA was isolated from blastemas of control and retinoic acid (RA) treated animals during the following limb regeneration stages: initial dedifferentiation (ID), medium bud (MB), notch (N), and 3-finger bud (3-FB). Xenopus nuclear rDNA and axolotl 16S mitochondrial rDNA …
