Physical mapping integrated with syntenic analysis to characterize the gene space of the long arm of wheat chromosome 1A [PDF]
, 2013 Background: Bread wheat (Triticum aestivum L.) is one of the most important crops worldwide and its production faces pressing challenges, the solution of which demands genome information. However, the large, highly repetitive hexaploid wheat genome has

Chromosome Structure: Coiling up chromosomes [PDF]
Current Biology, 1995 The mechanism by which eukaryotic chromosomes condense as cells enter mitosis has long been inaccessible to molecular biologists. An important clue has now been provided by a ubiquitous protein family, the SMCs.

Errors in chromosome segregation during oogenesis and early embryogenesis [PDF]
, 2010 Errors in chromosome segregation occurring during human oogenesis and early embryogenesis are very common. Meiotic chromosome development during oogenesis is subdivided into three distinct phases.

ChrSNet: Chromosome Straightening using Self-attention Guided Networks [PDF]
arXiv, 2022 Karyotyping is an important procedure to assess the possible existence of chromosomal abnormalities. However, because of the non-rigid nature, chromosomes are usually heavily curved in microscopic images and such deformed shapes hinder the chromosome analysis for cytogeneticists.

A conserved filamentous assembly underlies the structure of the meiotic chromosome axis. [PDF]
, 2019 The meiotic chromosome axis plays key roles in meiotic chromosome organization and recombination, yet the underlying protein components of this structure are highly diverged.

Chromosome cohesion: A polymerase for chromosome bridges [PDF]
Current Biology, 2000 How do cells ensure that sister chromatids produced during DNA replication stay connected with each other until their separation in anaphase? New insight is provided by the discovery of DNA polymerase kappa, which has been found to be required for building the connections between sister chromatids.

A family case of fertile human 45,X,psu dic(15;Y) males [PDF]
, 2006 We report on a familial case including four male probands from three generations with a 45,X,psu dic(15;Y)(p11.2;q12) karyotype. 45,X is usually associated with a female phenotype and only rarely with maleness, due to translocation of small Y chromosomal

The chromosomes of the Filariae [PDF]
Filaria Journal, 2005 An understanding of the nature of the chromosomes of the filariae is expected to greatly assist the future interpretation of genome data. Filarial development is not eutelic, and there does not seem to be a fixed number of cell divisions in the way that there is in Caenorhabditis.

Chromosome breakpoint distribution of damage induced in peripheral blood lymphocytes by densely ionising radiation [PDF]
, 2006 Purpose: To assess the chromosomal breakpoint distribution in human peripheral blood lymphocytes (PBL) after exposure to a low dose of high linear energy transfer (LET) α-particles using the technique of multiplex fluorescence in situ hybridisation (m ...

Nature Communications, 2019 RAD51 assembly on single-stranded DNAs is an important step in the homology-dependent repair of DNA damage. Here authors reveal a role for the human RAD51 paralogue, SWSAP1, as a regulator of RAD51 assembly, by antagonizing RAD51 remodeller, FIGNL1 AAA +
