Characterization of ribosomal DNA (rDNA) in Drosophila arizonae
Genetics and Molecular Biology, 2000 Ribosomal DNA (rDNA) is a multigenic family composed of one or more clusters of repeating units (RU). Each unit consists of highly conserved sequences codifying 18S, 5.8S and 28S rRNA genes intercalated with poorly conserved regulatory sequences between ...

A single, multiplex PCR for differentiating all species of Trichinella
Parasite, 2001 The genus Trichinella is currently divided into seven species and at least three additional, unclassified genotypes, Trichinella T6, T8 and T9, where both T8 and T9 have been deemed very similar to T. britovi. Other than for the non-encapsulated species,

The unusual Gasteromycetes Lycogalopsis solmsii belongs to the gomphoid-phalloid group
Acta Mycologica, 2013 The rare tropical Gasteromycetes Lycogalopsis solmsii has been found twice at thirty years interval in the Singapore Botanic Gardens. From the most recent find a culture could be isolated, which allowed DNA extraction and sequencing of about 2000 bp from

Regulation of ribosomal DNA transcription by insulin [PDF]
American Journal of Physiology-Cell Physiology, 1998 The experiments reported here used 3T6-Swiss albino mouse fibroblasts and H4-II-E-C3 rat hepatoma cells as model systems to examine the mechanism(s) through which insulin regulates rDNA transcription. Serum starvation of 3T6 cells for 72 h resulted in a marked reduction in rDNA transcription.

Salt Effects on the Thermodynamics of a Frameshifting RNA Pseudoknot under Tension [PDF]
, 2016 Because of the potential link between -1 programmed ribosomal frameshifting and response of a pseudoknot (PK) RNA to force, a number of single molecule pulling experiments have been performed on PKs to decipher the mechanism of programmed ribosomal frameshifting.

NTRFINDER: A Software Tool to Find Nested Tandem Repeats [PDF]
arXiv, 2010 We introduce the software tool NTRFinder to find the complex repetitive structure in DNA we call a nested tandem repeat (NTR). An NTR is a recurrence of two or more distinct tandem motifs interspersed with each other. We propose that nested tandem repeats can be used as phylogenetic and population markers.

arXiv, 2017 Engineering shape and interactions of nanoscopic building blocks allows for the assembly of rationally designed macroscopic three-dimensional (3D) materials with spatial accuracy inaccessible to top-down fabrication methods. Owing to its sequence-specific interaction, DNA is often used as selective binder to connect metallic nanoparticles into highly ...

The role of the DNA damage response in zebrafish and cellular models of Diamond Blackfan anemia
Disease Models & Mechanisms, 2014 Ribosomal biogenesis involves the processing of pre-ribosomal RNA. A deficiency of some ribosomal proteins (RPs) impairs processing and causes Diamond Blackfan anemia (DBA), which is associated with anemia, congenital malformations and cancer.

A resource dependent protein synthesis model for evaluating synthetic circuits [PDF]
arXiv, 2016 Reliable in-silico design of synthetic gene networks necessitates novel approaches to model the process of protein synthesis under the influence of limited resources. We present such a novel protein synthesis model which originates from the Ribosome Flow Model and among other things describes the movement of RNA-polymerase and Ribosomes on mRNA and DNA
