DNA replication stress restricts ribosomal DNA copy number. [PDF]
Ribosomal RNAs (rRNAs) in budding yeast are encoded by ~100-200 repeats of a 9.1kb sequence arranged in tandem on chromosome XII, the ribosomal DNA (rDNA) locus.

Ribosomal DNA Copy Number Variation is Coupled with DNA Methylation Changes at the 45S rDNA Locus [PDF]
The human ribosomal DNA (rDNA) copy number (CN) has been challenging to analyse, and its sequence has been excluded from reference genomes due to its highly repetitive nature. The 45S rDNA locus encodes essential components of the cell, nevertheless rDNA

Genome-wide DNA methylation profiles and ribosomal DNA copy number at birth [PDF]
Ribosomal DNA copy number (rDNAcn) and DNA methylation are important modulators of the human genome, both studied in relation to overall cellular function, biological ageing, and disease development.

CX-5461 Preferentially Induces Top2α-Dependent DNA Breaks at Ribosomal DNA Loci [PDF]
While 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 ...

RNA polymerase I mutant affects ribosomal RNA processing and ribosomal DNA stability [PDF]
Transcription is a major contributor to genomic instability. The ribosomal RNA (rDNA) gene locus consists of a head-to-tail repeat of the most actively transcribed genes in the genome.

Isolation and study of morphology and phylogeny of arbuscular mycorrhizal fungi coexisting with the roots of some medicinal plants in Kerman province [PDF]
Objective Plants that have a symbiotic relationship with arbuscular mycorrhizal fungi (AMF) compared with non-mycorrhizal plants have a higher ability to resist against various biotic and abiotic environmental stresses such as drought, salinity, pests ...

Characterization of Yeast Ribosomal DNA [PDF]
High‐molecular‐weight yeast ribosomal DNA, purified by preparative Hg2/Cs2SO4 gradient centrifugation, was characterized using RNA‐DNA hybridization, CsCl gradient analysis and denaturation‐renaturation experiments. The following conclusions are drawn from the results of these studies.

The harmful jellyfish Cyanea nozakii Kishinouye has frequently occurred on Korean coasts, and its blooms have caused serious ecological and economic damages. DNA sequences of the C. nozakii for molecular detection and discrimination are relatively scarce.

Heterogeneity of Pumpkin Ribosomal DNA [PDF]
The ribosomal DNA (rDNA) of Cucurbita pepo L. has been found to consist of tandemly arrayed repeat units, most of which are 10 kilobases in length. Thirty-six repeat units, cloned into the HindIII site of pACYC 177, fall into seven classes which differ from each other in length and/or nucleotide sequence.
