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

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.

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1977
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.

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

Incorporating activity of ribosomes and integrity of ribosomal RNA
Biochemical and Biophysical Research Communications, 1970Abstract The interrelationship between the amino acid incorporating ability and the state of ribosomal-RNA in ribonuclease treated rat liver ribosomes was studied. It was shown that ribosomes containing no or only negligible amounts of 28 S ribosomal-RNA retained at least 30 per cent of their original incorporating activity /measured without addition

Ribosomal RNA: the message or matrix for ribosomal proteins
Canadian Journal of Biochemistry, 1976The known nucleotide sequence of Escherichia coli 16S ribosomal RNA has been converted to amino acid sequences in all possible ways, and compared to known ribosomal protein sequences. The degree of similarity is precisely what one would expect by chance alone, providing additional evidence that ribosomal proteins cannot be coded for by ribosomal RNA.

Ribosomal and non-ribosomal RNA synthesis in vitro
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1975The synthesis of total and ribosomal RNA using nucleoids of Escherichia coli as template was measured; of the total RNA synthesized by endogenous RNA polymerase which only completes chains, and added RNA polymerase which initiates new chains, 50-70 and 3-5%, repectively, was rRNA.
