DeRisi and colleagues present a creative application for Cas9 in vitro, using it to deplete unwanted sequence from DNA libraries. It seems plausible that the in vitro use of CRISPR/Cas9 has unrealized potential to revolutionize the practice of molecular biology well beyond genome editing.
Mitochondrial DNA mutations are well recognized as an important cause of disease, with over two hundred variants in the protein encoding and mt-tRNA genes associated with human disorders. In contrast, the two genes encoding the mitochondrial rRNAs (mt-rRNAs) have been studied in far less detail. This is because establishing the pathogenicity of mt-...
Molecular phylogenetics and evolution
The Helicoidea is one of the most diverse superfamilies of terrestrial land snails. In this study we present a molecular phylogeny of the western Palaearctic Helicoidea obtained by means of neighbor joining, maximum likelihood and Bayesian analysis of the mitochondrial 16S rRNA gene fragment and the nuclear rRNA gene cluster including the 3' end of...

In order to investigate the extent of the genetic variation in the DNA sequences of Sarcoptes scabiei, mite populations collected on Alpine chamois (Rupicapra rupicapra), Pyrenean chamois (Rupicapra pyrenaica) and red fox (Vulpes vulpes) from different localities of Italy and Spain were studied. Sequence analyses were carried out on the second inte...
Nucleotide sequences of a subregion of the mitochondrial 16S ribosomal RNA gene of 10 species of a blackfly subgenus Simulium (Nevermannia), which include four species of feuerborni species-group, two species of ruficorne species-group, three species of vernum species-group and an ungrouped species (S. konoi), were determined. Phylogenetic analyses...

The superfamily of kangaroos (Macropodoidea) is comprised of the subfamilies Propleopinae, Hypsiprymnodontinae, Paleopotoroinae, Potoroinae, Bulungamayinae, Balbarinae, Macropodinae, and Sthenurinae. Of these, Hypsiprymnodontinae, Potoroinae, and Macropodinae are extant. Competing phylogenetic hypotheses unite potoroines with either hypsiprymnodont...
