The Monophyly of Brachyuran Crabs: A Phylogenetic Study Based on 18S rRNA

Systematic Biology, 1992
A molecular approach was used to test hypotheses about the phylogeny of selected brachyuran crabs. Partial 18S ribosomal (r) RNA and rDNA sequences, ranging in length from 950 to 1,779 nucleotides, were obtained for 12 decapod crustaceans, 10 of which are generally considered to be brachyurans. Pairwise sequence-divergence estimates ranged from 0.5% to

Geographical variation in 18S rRNA gene sequence of Cryptosporidium parvum

International Journal for Parasitology, 1994
Using 18S rRNA as a probe, an EcoR1 fragment containing 1507 nt of 18S rRNA from C. parvum was identified, cloned and sequenced. Comparison of this sequence with the partial sequence of the small subunit rRNA of Cryptosporidium published by Johnson, Fielke, Lumb & Baverstock (International Journal for Parasitology 20: 141-147, 1990) and 1516 bp of the ...

26S and 18S rRNA synthesis in bobbed mutants of Drosophila melanogaster

Biochimie, 1981
For the most part, bobbed mutations of Drosophila melanogaster consist of deletions of 26S and 18S rDNA located on the X and Y chromosomes. Studies on the synthesis of rRNA of third instar larvae and one day old adult females of three severe bobbed genotypes, indicate that no decrease can be detected, compared ot wild type strains.

Methylation of snRNAs and 18S rRNA of Novikoff heptoma

1982
In the biosynthesis of mature snRNAs and rRNAs, RNA methylation is one of the important mechanisms involved in their posttranscriptional modifications. The processes of RNA methylation are catalyzed by RNA methylases which specifically recognize methylation sites. This enzymatic recognition of methylating sites is specific for particular species of RNA
