Meiotic Chromosome Dynamics in Zebrafish
Frontiers in Cell and Developmental Biology, 2021 Recent studies in zebrafish have revealed key features of meiotic chromosome dynamics, including clustering of telomeres in the bouquet configuration, biogenesis of chromosome axis structures, and the assembly and disassembly of the synaptonemal complex ...

GenomeFingerprinter and universal genome fingerprint analysis for systematic comparative genomics [PDF]
, 2013 How to compare whole genome sequences at large scale has not been achieved via conventional methods based on pair-wisely base-to-base comparison; nevertheless, no attention was paid to handle in-one-sitting a number of genomes crossing genetic category ...

Double in situ hybridization in combination with digital image analysis: A new approach to study interphase chromosome topography [PDF]
, 1989 Double in situ hybridization with mercurated and biotinylated chromosome specific DNA probes in combination with digital image analysis provides a new approach to compare the distribution of homologous and nonhomologous chromosome targets within ...

A recurrent translocation is mediated by homologous recombination between HERV-H elements
Molecular Cytogenetics, 2012 Background Chromosome rearrangements are caused by many mutational mechanisms; of these, recurrent rearrangements can be particularly informative for teasing apart DNA sequence-specific factors.

The Origin of a New Sex Chromosome by Introgression between Two Stickleback Fishes. [PDF]
, 2019 Introgression is increasingly recognized as a source of genetic diversity that fuels adaptation. Its role in the evolution of sex chromosomes, however, is not well known. Here, we confirm the hypothesis that the Y chromosome in the ninespine stickleback,

Condensin II resolves chromosomal associations to enable anaphase I segregation in Drosophila male meiosis. [PDF]
PLoS Genetics, 2008 Several meiotic processes ensure faithful chromosome segregation to create haploid gametes. Errors to any one of these processes can lead to zygotic aneuploidy with the potential for developmental abnormalities.

Securin Is Not Required for Chromosomal Stability in Human Cells [PDF]
, 2005 Abnormalities of chromosome number are frequently observed in cancers. The mechanisms regulating chromosome segregation in human cells are therefore of great interest.

The BRCA Tumor Suppressor Network in Chromosome Damage Repair by Homologous Recombination.
Annual Review of Biochemistry, 2019 Mutations in the BRCA1 and BRCA2 genes predispose afflicted individuals to breast, ovarian, and other cancers. The BRCA-encoded products form complexes with other tumor suppressor proteins and with the recombinase enzyme RAD51 to mediate chromosome ...
