Discontinuous transcription of ribosomal DNA in human cells.
PLoS ONE, 2020 Numerous studies show that various genes in all kinds of organisms are transcribed discontinuously, i.e. in short bursts or pulses with periods of inactivity between them.

PCR primers for metazoan nuclear 18S and 28S ribosomal DNA sequences. [PDF]
PLoS ONE, 2012 BACKGROUND: Metagenetic analyses, which amplify and sequence target marker DNA regions from environmental samples, are increasingly employed to assess the biodiversity of communities of small organisms. Using this approach, our understanding of microbial

The Epigenetic Pathways to Ribosomal DNA Silencing [PDF]
Microbiology and Molecular Biology Reviews, 2016 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

CX-5461 Preferentially Induces Top2α-Dependent DNA Breaks at Ribosomal DNA Loci
BiomedicinesWhile genotoxic chemotherapeutic agents are among the most effective tools to combat cancer, they are often associated with severe adverse effects caused by indiscriminate DNA damage in non-tumor tissue as well as increased risk of secondary ...

Studies on ribosomal DNA in cetaceans (whales) [PDF]
Hereditas, 2008 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.

Morphological and molecular identification of filamentous fungi isolated from cosmetic powders
Brazilian Archives of Biology and Technology, 2012 Seven fungi were isolated from 50 samples of cosmetic powders. Morphological analyses and ribosomal DNA Internal Transcribed Spacers sequencing were performed which allowed the discrimination of the isolated fungi as Aspergillus fumigatus, Penicillium sp.

Catalogue of fungi in China 2. Ramaria from northern China
MycologyThe species of Ramaria are coralloid-fungi with intricately branched and vividly coloured basidiomata. There are many studies on the genus Ramaria in China, but molecular phylogenetic analysis is rarely employed.

Replication of Ribosomal DNA in Xenopus laevis [PDF]
European Journal of Biochemistry, 1981 The study of the localization of the replication origins of rDNA in Xenopus laevis has been approached by two different methods. 1. The DNA of X. laevis larvae was fractionated by CsCl gradient centrifugation in bulk and ribosomal DNA and examined in the electron microscope.

Catalytic and non-catalytic roles for the mono-ADP-ribosyltransferase Arr in the mycobacterial DNA damage response. [PDF]
PLoS ONE, 2011 Recent evidence indicates that the mycobacterial response to DNA double strand breaks (DSBs) differs substantially from previously characterized bacteria.
