Evaluation of COI and ITS2 sequences ability to distinguish Lysiphlebus fabarum and Lysiphlebus confusus (Hymenoptera: Aphidiidae) [PDF]
All wasp species in the genus Lysiphlebus Förster are solitary endoparasitoids of aphids andconsidered a taxonomically difficult group. In this study a part of COI and ITS2 was used to distinguishtwo closely related species L.

Roles of ribosomal proteins in hematologic disorders and cancers: a review
. Ribosomes are important organelles for synthesizing proteins in cells. They are composed of ribosomal RNA and more than 80 ribosomal proteins. It is well known that an essential function of ribosomal proteins is to participate in protein translation ...

Two groups of taxa can be distinguished within the genus Lolium L. based on the pollination system, chromosome size, chromosomal location of nrDNA (5S and 35S (18S-5.8S-26S)] and nrDNA phylogeny.

Quantitation of Human Ribosomal DNA: Hybridization of Human DNA with Ribosomal RNA for Quantitation and Fractionation [PDF]
Extract: Quantitation of human genes for ribosomal RNA (rRNA) was possible by molecular DNA/RNA hybridization on nitrocellulose discs. Labeled ribosomal RNA hybridizes with an average of 14 × 10-5 of the total human DNA. If we assume that the diploid cell contains 5.5 × 1012 daltons of DNA, the ribosomal RNA hybridizes with 7.7 × 108 daltons of ...

Introduction: Mild cognitive impairments (MCI) accompanying aging are associated with oxidative stress. The ability of cells to respond to stress is determined by the protein synthesis level, which depends on the ribosomes number.

Modular Golden Gate Assembly of Linear DNA Templates for Cell-free Prototyping [PDF]
Cell-free transcription and translation (TXTL) systems have emerged as a powerful tool for testing genetic regulatory elements and circuits. Cell-free prototyping can dramatically accelerate the design-build-test cycle of new functions in synthetic biology, in particular when linear DNA templates are used.

First Report of Hemicriconemoides kanayaensis (Nematoda: Criconematidae) on Tea Plantations in Iran
During a nematode survey in Iran, an abundant population of sheathoid, migratory, root-ectoparasitic nematodes was recovered from a tea, Camellia sinensis (L.), Kuntze plantation for the first time. Morphological and molecular characterization identified

The Epigenetic Pathways to Ribosomal DNA Silencing [PDF]
SUMMARY Heterochromatin is the transcriptionally repressed portion of eukaryotic chromatin that maintains a condensed appearance throughout the cell cycle. At sites of ribosomal DNA (rDNA) heterochromatin, epigenetic states contribute to gene silencing and genome stability, which are required for proper chromosome segregation and

Studies on ribosomal DNA in cetaceans (whales) [PDF]
ARNASON U. and WIDEGREN, B. 1984. Studies on ribosomal DNA in cetaceans (whales).—Hereditas 101:149–154. Lund, Sweden. ISSN 0018–0661. Ribosomal DNA (rDNA) of 4 mysticetes and 10 odontocetes were studied by Southern blot hybridization. The material represented all extant cetacean families except the gray whales.
