Slipped-Strand Mispairing at Noncontiguous Repeats in Poecilia reticulata: A Model for Minisatellite Birth [PDF]

open access: yesGenetics, 2000
Abstract The standard slipped-strand mispairing (SSM) model for the formation of variable number tandem repeats (VNTRs) proposes that a few tandem repeats, produced by chance mutations, provide the “raw material” for VNTR expansion. However, this model is unlikely to explain the formation of VNTRs with long motifs (e.g., minisatellites),

Determination of Earth's Static Gravity Field Using Quantum Gravity Satellites at Very Low Earth Orbit

open access: yesEarth and Space Science, Volume 13, Issue 10, October 2026.
Abstract Very Low Earth Orbit (VLEO) satellite platforms and quantum‐optical sensing technologies may provide new observation approaches for improving Earth's static gravity field models. This study conceptually assesses their potential contribution through a two‐tier closed‐loop simulation framework.

Terminal Restriction Fragments (TRF) Method to Analyze Telomere Lengths

open access: yesBio-Protocol, 2015
Chromosome ends - telomeres - are a focus of intensive research due to their importance for the maintenance of chromosome stability. Their shortening due to incomplete replication functions as a molecular clock counting the number of cell divisions, and ...

A Time‐Continuous Model of the 3D Ionospheric Current System and Associated Magnetic Fields in the Diurnal Variation Band

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Ionospheric currents and their associated magnetic perturbations are difficult to predict due to the high variability of their driving mechanisms. In addition, the 3D structure of the currents is challenging to unravel due to the lack of direct observations within the current flow region, particularly in the E $E$‐layer.

The architecture of the Plasmodiophora brassicae nuclear and mitochondrial genomes

open access: yesScientific Reports, 2019
Plasmodiophora brassicae is a soil-borne pathogen that attacks roots of cruciferous plants causing clubroot disease. The pathogen belongs to the Plasmodiophorida order in Phytomyxea. Here we used long-read SMRT technology to clarify the P.

Identification and characterization of a minisatellite contained within a novel miniature inverted-repeat transposable element (MITE) of Porphyromonas gingivalis

open access: yesMobile DNA, 2015
Repetitive regions of DNA and transposable elements have been found to constitute large percentages of eukaryotic and prokaryotic genomes. Such elements are known to be involved in transcriptional regulation, host-pathogen interactions and genome ...

Structural characterization of supercoiled DNA containing a minisatellite repeat that has polypurine/polypyrimidine stretch [PDF]

open access: yesNucleic Acids Symposium Series, 2007
The pUC19 derivative pAL79 contains six tandem repeats of a 30-bp unit sequence. Supercoiled pAL79 molecules show aberrant electrophoretic mobility under acidic conditions, and microscopic analysis suggests pAL79 molecules conform to tight plectonemes when deposited on a substrate under acidic conditions.

Evaluation and selection of tandem repeat loci for a Brucella MLVA typing assay

open access: yesBMC Microbiology, 2006
Background The classification of Brucella into species and biovars relies on phenotypic characteristics and sometimes raises difficulties in the interpretation of the results due to an absence of standardization of the typing reagents.

Characterization of Chromosome-Specific Microsatellite Repeats and Telomere Repeats Based on Low Coverage Whole Genome Sequence Reads in Panax ginseng

open access: yes, 2018
Repetitive DNA elements are ubiquitous in plant genomes. Although repeats provide relevant information for cytogenetic, evolutionary, and genomic studies, identifying and characterizing their sequence and chromosomal distribution are not always easily ...
