Probing the Secondary Structure of Expansion Segment ES6 in 18S Ribosomal RNA

Biochemistry, 2006
Expansion segment ES6 in 18S ribosomal RNA is, unlike many other expansion segments, present in all eukaryotes. The available data suggest that ES6 is located on the surface of the small ribosomal subunit. Here we have analyzed the secondary structure of the complete ES6 sequence in intact ribosomes from three eukaryotes, wheat, yeast, and mouse ...

Studies on the role of 23 s nucleolar RNA as an intermediate in the synthesis of 18 s ribosomal RNA

Journal of Molecular Biology, 1971
Abstract From whole nucleolar RNA of Novikoff hepatoma cells, a single symmetrical peak of 23 s RNA was obtained by repeated sucrose density-gradient centrifugations. Hybridization experiments showed that nucleolar 23 s RNA is composed of 18 s ribosomal RNA and other RNA segments.

A T1 ribonuclease fragment present in 18 S ribosomal RNA of Novikoff rat ascites hepatoma cells and absent from 18 S ribosomal RNA of HeLa cells

Journal of Molecular Biology, 1975
Oligonucleotides, produced by digestion of 32P-labeled 18 S ribosomal RNAs from Novikoff rat ascites hepatoma and HeLa cells with T1 ribonuclease, were mapped by homochromatography fingerprinting. The fingerprint patterns from the two rRNAs were quite similar and 18 of the separated large fragments had corresponding migrations but one fragment present ...

The human 18S ribosomal RNA gene: evolution and stability.

American journal of human genetics, 1986
We report the 1,870-base-pair primary sequence of a human 18S rRNA gene and propose a secondary structure based on this sequence and the general mammalian structure. A basic secondary structure for the small subunit rRNA has been preserved throughout evolution by compensatory and neutral base changes in double-stranded regions.

The nuclear 18S ribosomal RNA gene as a source of phylogenetic information in the genus Taenia

Parasitology Research, 2012
Most species of the genus Taenia are of considerable medical and veterinary significance. In this study, complete nuclear 18S rRNA gene sequences were obtained from seven members of genus Taenia [Taenia multiceps, Taenia saginata, Taenia asiatica, Taenia solium, Taenia pisiformis, Taenia hydatigena, and Taenia taeniaeformis] and a phylogeny inferred ...

Molecular Phylogeny of Labyrinthulids and Thraustochytrids Based On the Sequencing of 18s Ribosomal Rna Gene

Journal of Eukaryotic Microbiology, 1999
ABSTRACT Labyrinthulids and thraustochytrids are unicellular heterotrophs, formerly considered as fungi, but presently are recognized as members in the stramenopiles of the kingdom Protista sensu lato. We determined the 18S ribpsomal RNA gene sequences of 14 strains from different species of the six genera and analyzed the molecular phylogenetic ...
