Characterization of Yeast Ribosomal DNA [PDF]

European Journal of Biochemistry, 1975
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.

Heterogeneity of Pumpkin Ribosomal DNA [PDF]

Plant Physiology, 1983
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.

Ribosomal DNA heterochromatin in plants [PDF]

Cytogenetic and Genome Research, 2005
The aim of this review is to integrate earlier results and recent findings to present the current state-of-the-art vision concerning the dynamic behavior of the ribosomal DNA (rDNA) fraction in plants. The global organization and behavioral features of rDNA make it a most useful system to analyse the relationship between chromatin topology and gene ...

DNA Binding by the Ribosomal DNA Transcription Factor Rrn3 Is Essential for Ribosomal DNA Transcription [PDF]

Journal of Biological Chemistry, 2013
The human homologue of yeast Rrn3 is an RNA polymerase I-associated transcription factor that is essential for ribosomal DNA (rDNA) transcription. The generally accepted model is that Rrn3 functions as a bridge between RNA polymerase I and the transcription factors bound to the committed template. In this model Rrn3 would mediate an interaction between

Ribosomal DNA-connecting ribosome biogenesis and chromosome biology [PDF]

Chromosome Research, 2019
Ribosomal DNA, the topic of this special issue, has long fascinated biologists. The RNA products of the ribosomal DNA are the ribosomal RNAs that are part of the ribosome. In this special issue, we focus on the sequence, molecular organization, repair, stability, copy number, and peculiar genetics of this region of the genome.

Challenges and Approaches to Genotyping Repetitive DNA

G3: Genes, Genomes, Genetics, 2020
Individuals within a species can exhibit vast variation in copy number of repetitive DNA elements. This variation may contribute to complex traits such as lifespan and disease, yet it is only infrequently considered in genotype-phenotype associations ...

Smc5/6: a link between DNA repair and unidirectional replication? [PDF]

, 2008
Of the three structural maintenance of chromosome (SMC) complexes, two directly regulate chromosome dynamics. The third, Smc5/6, functions mainly in homologous recombination and in completing DNA replication.

Drug hypersensitivity caused by alteration of the MHC-presented self-peptide repertoire [PDF]

, 2012
Idiosyncratic adverse drug reactions are unpredictable, dose independent and potentially life threatening; this makes them a major factor contributing to the cost and uncertainty of drug development. Clinical data suggest that many such reactions involve
