Dynamic large-scale chromosomal rearrangements fuel rapid adaptation in yeast populations. [PDF]

open access: yesPLoS Genetics, 2013
Large-scale genome rearrangements have been observed in cells adapting to various selective conditions during laboratory evolution experiments. However, it remains unclear whether these types of mutations can be stably maintained in populations and how ...

Genome organization influences partner selection for chromosomal rearrangements [PDF]

open access: yes, 2010
Chromosomal rearrangements occur as a consequence of the erroneous repair of DNA double-stranded breaks, and often underlie disease. The recurrent detection of specific tumorigenic rearrangements suggests that there is a mechanism behind chromosomal ...

Comparative cytogenetics in three species of Wood-Warblers (Aves: Passeriformes: Parulidae) reveal divergent banding patterns and chromatic heterogeneity for the W chromosome

open access: yesCaryologia, 2021
Chromosomal rearrangements are an important process in the evolution of species. It is assumed that these rearrangements occur near repetitive sequences and heterochromatic regions.

DNA double-strand break repair pathways, chromosomal rearrangements and cancer. [PDF]

open access: yes, 2011
Chromosomal rearrangements, which can lead to oncogene activation and tumour suppressor loss, are a hallmark of cancer cells. Such outcomes can result from both the repair and misrepair of DNA ends, which arise from a variety of lesions including DNA ...

Chromosomal Speciation Revisited: Modes of Diversification in Australian Morabine Grasshoppers (Vandiemenella, viatica Species Group)

open access: yesInsects, 2011
Chromosomal rearrangements can alter the rate and patterns of gene flow within or between species through a reduction in the fitness of chromosomal hybrids or by reducing recombination rates in rearranged areas of the genome.

Hi-C as a tool for precise detection and characterisation of chromosomal rearrangements and copy number variation in human tumours

open access: yesGenome Biology, 2017
Chromosomal rearrangements occur constitutionally in the general population and somatically in the majority of cancers. Detection of balanced rearrangements, such as reciprocal translocations and inversions, is troublesome, which is particularly ...

Establishment of a Cre-loxP System Based on a Leaky LAC4 Promoter and an Unstable panARS Element in Kluyveromyces marxianus

open access: yesMicroorganisms, 2022
The Cre-loxP system produces structural variations, such as deletion, duplication, inversion and translocation, at specific loci and induces chromosomal rearrangements in the genome.

Fluorescence in situ hybridization to chromosomes as a tool to understand human and primate genome evolution [PDF]

open access: yes, 2005
For the last 15 years molecular cytogenetic techniques have been extensively used to study primate evolution. Molecular probes were helpful to distinguish mammalian chromosomes and chromosome segments on the basis of their DNA content rather than solely ...

Stimulation of Chromosomal Rearrangements by Ribonucleotides [PDF]

open access: yesGenetics, 2015
AbstractWe show by whole genome sequence analysis that loss of RNase H2 activity increases loss of heterozygosity (LOH) in Saccharomyces cerevisiae diploid strains harboring the pol2-M644G allele encoding a mutant version of DNA polymerase ε that increases ribonucleotide incorporation.

Introducing defined chromosomal rearrangements into the mouse genome [PDF]

open access: yes, 2001
Chromosomal rearrangements have been instrumental in genetic studies in Drosophila. Visibly marked deficiencies (deletions) are used in mapping studies and region-specific mutagenesis screens by providing segmental haploidy required to uncover recessive ...
