Tetrapod phylogeny as inferred from 18S and 28S ribosomal-RNA sequence comparisons
The superclass Tetrapoda consists of several well defined monophyletic taxa: Anura, Urodela, Gymnophiona, Testudinata, Squamata, Rhychocephalia, Crocodilia, Aves and Mammalia. The relationships among these groups, however, is controversial. Neither paleontological evidence nor morphological, …

A Census of Human RNA-Binding Proteins and Characterization of the DEDDh RNA Exonuclease NEF-sp in the 3' End Maturation of 28S Ribosomal RNA
… NEF-sp and characterized its function in pre-28S ribosomal RNA processing. Ribosomal RNA biogenesis requires a series of endo- and exonucleolytic processing steps for the production of mature rRNAs. Although the mechanism of 28S 3' end rRNA maturation remains largely unknown in higher …

In silico investigation of the mechanism of ricin-catalysed depurination reaction and design of novel ricin inhibitors
… adenine (A-4324) of the GAGA tetra loop of 28S ribosomal RNA. Despite this destructive feature, ricin has been touted as a potential therapeutic agent where applications such as immunotoxins to treat cancer, AIDS and other diseases are actively being pursued. However, the prime challenge in …

A Molecular Phylogenetic Assessment of the North American Lichen Tiger Moths (Lepidoptera; Erebidae; Arctiinae; Lithosiini) with Life History Observations and a Description of a New Species from Central Arizona
… Lepidoptera: cytochrome oxidase subunit I (COI), ribosomal protein S5 (RPS5) and the large subunit 28S ribosomal DNA (28S). Results provide new insights as to how representatives of the 16 genera and 63 species that comprise the lithosiine fauna of the US are related. We also investigated a unique …

Next-Generation Approaches to Understanding the Diversity and Evolution of Marine Fungi
… Channel using high-throughput sequencing of 18S ribosomal DNA. In addition to characterizing the taxonomic and phylogenetic diversity of planktonic protists, I also estimate the niche breadth of the taxa observed and infer ecological roles and trophic modes to examine if and how functional guilds …

Characterization and Engineering of Transposons for Genome Editing
… can be used to perform DNA insertion into human 28S ribosomal DNA (rDNA) repeats and validate this strategy for delivering a functional transgene. We also demonstrate that R2bm’s target site can be changed through association with a reprogrammable DNA-binding protein like SpCas9, enabling …

Molecular and Field Analyses of Bathyplectes spp. (Hymenoptera: Ichneumonidae) in Alfalfa Systems in Virginia
… were obtained for the D2–D3 region of the 28S ribosomal DNA (28S rDNA) gene; sequence identity between B. anurus and B. curculionis was 96.6%. The 28S rDNA sequences were also obtained for another Bathyplectes species, possibly B. stenostigma, and for four taxa of Hymenoptera that …

Systematics and biogeography of leafhoppers in Madagascar
… within each lineage, different domains of 28S ribosomal RNA (D2, D6, D8, D9, D10), Histone (H3), 12SrRNA (12S) and Cytochrome Oxidase II were sequenced. Phylogenetic analyses based on Parsimony, Maximum Likelihood and Bayesian approaches recovered congruent topologies for each dataset. In …
