Ribosomal RNA and ribosomal proteins in corynebacteria
Journal of Biotechnology, 2003Ribosomal RNAs (rRNAs) (16S, 23S, 5S) encoded by the rrn operons and ribosomal proteins play a very important role in the formation of ribosomes and in the control of translation. Five copies of the rrn operon were reported by hybridization studies in Brevibacterium (Corynebacterium) lactofermentum but the genome sequence of Corynebacterium glutamicum ...

Ribosomal RNA on the Surface of Ribosomes
Science, 1963Ribonuclease from pancreas releases nucleotide from Escherichia coli ribosomes while not altering significantly the base composition of the total ribosomal RNA. Ribonuclease hydrolyzes ribsomal RNA without destroying the structure of 70 S or 30 S and 50 S

Ribosomal RNA Synthesis and RNA Polymerase
Nature, 1970MULTIPLE forms of RNA polymerase activity have been isolated from developing sea-urchin embryos, rat liver nuclei and calf thymus1–3. The molecular basis of this heterogeneity is at present unknown but, whatever its basis, the crucial question seems to be whether different enzymes copy different genes.

Messenger RNA movement on the ribosome
Molecular Biology, 2007Recent X-ray and cryo-EM studies of 70S ribosome complexes containing different types of messenger RNAs (mRNA) and transfer RNA (tRNA) have been reviewed. Changes of the mRNA path on the ribosome at initiation and elongation states have been described.

1971
Publisher Summary This chapter reviews that the ribosomal cistrons of both bacteria and eukaryotes, with their unique and well-defined characteristics, have increasingly attracted the attention of biochemists and geneticists. It discusses that the arrangement of the ribosomal cistrons on the chromosomal DNA, and they have been mapped in some detail ...

On the evolution of ribosomal RNA
Journal of Molecular Evolution, 1987Despite the availability of a rapidly growing ribosomal RNA database that now includes organisms in all three primary lines of descent (eubacteria, archaebacteria, and eukaryotes), theoretical treatment of the evolution of the ribosomal RNAs has lagged behind that of the protein genes.

The size and the location of the ribosomal RNA segments in ribosomal precursor RNA of yeast
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1971Abstract The order of the different segments of the 42-S ribosomal precursor RNA of yeast was investigated. For that purpose first the lengths of the rRNA stretches were measured. These were inferred from the relative amounts of oligonucleotides present in complete pancreatic ribonuclease digests of the two large rRNA components, and in this way were

1. The G + C content of ribosomal RNA of animals seems correlated with the length of periods required for maturation of those organisms. 2. In Protostomes of the animal kingdom, the size of the 28S rRNA molecule does not seem to correlate with the evolutionary stage of the organism. 3.

Regulation of ribosomal RNA synthesis
Advances in Enzyme Regulation, 1969Abstract Levorphanol, a synthetic morphine, is known as a potent inhibitor for bacterial ribosomal RNA. Spermidine has an antagonistic effect on this inhibition. The authors applied Levorphanol on the RNA synthesis in liver cells. Levorphanol specifically inhibits the nucleolar ribosomal RNA synthesis.
