Phylogenetic studies on three Helicotylenchus species based on 28S rDNA and mtCOI sequence data
Journal of Nematology, 2019 To facilitate the process of spiral nematode species delineation, populations of Helicotylenchus canadensis, H. pseudorobustus, and H. varicaudatus deriving from various locations and diverse natural and anthropogenic environments from Poland were ...

Memorias do Instituto Oswaldo Cruz, 2013 As the distribution of Candida species and their susceptibility to antifungal agents have changed, a new means of accurately and rapidly identifying these species is necessary for the successful early resolution of infection and the subsequent reduction ...

Pareto optimal fronts of kinetic proofreading [PDF]
, 2022 Biological processes such as DNA replication, RNA transcription, and protein translation show remarkable speed and accuracy in selecting the right substrate from pools of chemically identical molecules. This result is obtained by nonequilibrium reactions that dissipate chemical energy.

The Amplified Ribosomal DNA of Dytiscid Beetles [PDF]
Proceedings of the National Academy of Sciences, 1974 During oogenesis in many animals there is a massive extrachromosomal synthesis of the genes for ribosomal RNA. In Dytiscid beetles, as in the toad Xenopus , the amplified ribosomal DNA occurs as circular molecules of different sizes. The circles fall into size classes that are integral multiples of a unit circle. It

Early life stress inhibits expression of ribosomal RNA in the developing hippocampus. [PDF]
PLoS ONE, 2014 Children that are exposed to abuse or neglect show abnormal hippocampal function. However, the developmental mechanisms by which early life stress (ELS) impairs normal hippocampal development have not been elucidated. Here we propose that exposure to ELS

Frontiers in Oncology, 2022 Next-generation sequencing and bioinformatics analyses have clearly revealed the roles of mitochondrial ribosomal genes in cancer development. Mitochondrial ribosomes are composed of three RNA components encoded by mitochondrial DNA and 82 specific ...

Neurodegeneration-associated instability of ribosomal DNA
Biochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, 2014 Homologous recombination (HR)-mediated instability of the repetitively organized ribosomal DNA (rDNA) has been proposed as a mediator of cell senescence in yeast triggering the DNA damage response. High individual variability in the content of human rDNA suggests that this genomic region remained relatively unstable throughout evolution.

Ribosomal DNA magnification in Saccharomyces cerevisiae [PDF]
Journal of Bacteriology, 1978 Strains monosomic for chromosome I of Saccharomyces cerevisiae contain 25 to 35% fewer rRNA genes than do normal diploid strains. When these strains are repeatedly subcultured, colonies are isolated that have magnified their number of rRNA genes to the diploid amount while remaining monosomic for chromosome I.

Alterations of the mitochondrial proteome caused by the absence of mitochondrial DNA: A proteomic view [PDF]
Electrophoresis 27 (04/2006) 1574-83, 2006 The proper functioning of mitochondria requires that both the mitochondrial and the nuclear genome are functional. To investigate the importance of the mitochondrial genome, which encodes only 13 subunits of the respiratory complexes, the mitochondrial rRNAs and a few tRNAs, we performed a comparative study on the 143B cell line and on its Rho-0 ...
