TreeOTU: Operational Taxonomic Unit Classification Based on Phylogenetic Trees [PDF]
arXiv, 2013 Our current understanding of the taxonomic and phylogenetic diversity of cellular organisms, especially the bacteria and archaea, is mostly based upon studies of sequences of the small- subunit rRNAs (ssu-rRNAs). To address the limitation of ssu-rRNA as a phylogenetic marker, such as copy number variation among organisms and complications introduced by

The Expansion Segments of 28S Ribosomal RNA Extensively Match Human Messenger RNAs
Frontiers in Genetics, 2018 Eukaryote ribosomal RNAs (rRNAs) have expanded in the course of phylogeny by addition of nucleotides in specific insertion areas, the expansion segments.

Microbiome profiling by Illumina sequencing of combinatorial sequence-tagged PCR products [PDF]
, 2010 We developed a low-cost, high-throughput microbiome profiling method that uses combinatorial sequence tags attached to PCR primers that amplify the rRNA V6 region. Amplified PCR products are sequenced using an Illumina paired-end protocol to generate millions of overlapping reads.

ZooKeys, 2013 The sequences of 18S and 28S rDNAs have been used as molecular markers to resolve phylogenetic relationships of Heteroptera for two decades. The complete sequences of 18S rDNAs have been used in many studies, while in most studies only partial sequences ...

PCR-based detection of Plasmodium falciparum in saliva using mitochondrial cox3 and varATS primers
Tropical Medicine and Health, 2018 Background Sampling of saliva for diagnosing Plasmodium falciparum infections is a safe, non-invasive alternative to sampling of blood. However, the use of saliva presents a challenge because lower concentrations of parasite DNA are present in saliva ...

Translocation Properties of Primitive Molecular Machines and Their Relevance to the Structure of the Genetic Code [PDF]
arXiv, 2002 We address the question, related with the origin of the genetic code, of why are there three bases per codon in the translation to protein process. As a followup to our previous work, we approach this problem by considering the translocation properties of primitive molecular machines, which capture basic features of ribosomal/messenger RNA interactions,

Modelling Computational Resources for Next Generation Sequencing Bioinformatics Analysis of 16S rRNA Samples [PDF]
arXiv, 2015 In the rapidly evolving domain of next generation sequencing and bioinformatics analysis, data generation is one aspect that is increasing at a concomitant rate. The burden associated with processing large amounts of sequencing data has emphasised the need to allocate sufficient computing resources to complete analyses in the shortest possible time ...

Genetics and Molecular Biology, 2011 Chromosomal mapping of the butterfly lizards Leiolepis belliana belliana and L. boehmei was done using the 18S-28S and 5S rRNA genes and telomeric (TTAGGG)n sequences. The karyotype of L. b. belliana was 2n = 36, whereas that of L.

Biosaintifika: Journal of Biology & Biology Education, 2018 Protozoa species of Trichodina spp. may be found in most hatchery centers in Banyumas, Purbalingga, and Banjarnegara. However, the determination of Trichodina spp. types is still based on its body’s morphological variations, not yet molecular. A research
