Which one is the real matchmaker for the pair?
A fundamental question for meiosis is how homologous chromosomes (homologs) find each other and pair together to ensure homologous recombination and segregation.

Theory of phase segregation in DNA assemblies containing two different base pair sequence types [PDF]
Spontaneous pairing of homologous DNA sequences – a challenging subject in molecular biophysics, often referred to as ‘homology recognition’ – ha s been observed in vitro for several DNA system s a . One of th e se experiments involved liquid crystalline

Promotion of RAD51-mediated homologous DNA pairing by BRCA1-BARD1
The tumour suppressor complex BRCA1–BARD1 functions in the repair of DNA double-stranded breaks by homologous recombination. During this process, BRCA1–BARD1 facilitates the nucleolytic resection of DNA ends to generate a single-stranded template for the

A Role for RNA Synthesis in Homologous Pairing Events [PDF]
The relationship between RNA synthesis and homologous pairing in vitro, catalyzed by RecA protein, was examined by using an established strand transfer assay system. When a short DNA duplex is mixed with single-stranded circles, RecA protein promotes the transfer of the minus strand of the duplex onto the complementary region of the plus-strand circle,

Chromosome painting reveals asynaptic full alignment of homologs and HIM-8-dependent remodeling of X chromosome territories during Caenorhabditis elegans meiosis. [PDF]
During early meiotic prophase, a nucleus-wide reorganization leads to sorting of chromosomes into homologous pairs and to establishing associations between homologous chromosomes along their entire lengths.

PAR-TERRA directs homologous sex chromosome pairing
In mammals, homologous chromosomes rarely pair outside meiosis. One exception is the X chromosome, which transiently pairs during X-chromosome inactivation (XCI). How two chromosomes find each other in 3D space is not known.

Developing single-molecule TPM experiments for direct observation of successful RecA-mediated strand exchange reaction. [PDF]
RecA recombinases play a central role in homologous recombination. Once assembled on single-stranded (ss) DNA, RecA nucleoprotein filaments mediate the pairing of homologous DNA sequences and strand exchange processes.

Cytomolecular identification of individual wheat-wheat chromosome arm associations in wheat-rye hybrids [PDF]
Chromosome pairing in the meiotic metaphase I of wheatrye hybrids has been characterized by sequential genomic and fluorescent in situ hybridization allowing not only the discrimination of wheat and rye chromosomes, but also the identification of the

Optimizing the design of oligonucleotides for homology directed gene targeting. [PDF]
BACKGROUND: Gene targeting depends on the ability of cells to use homologous recombination to integrate exogenous DNA into their own genome. A robust mechanistic model of homologous recombination is necessary to fully exploit gene targeting for ...

Somatic Pairing in Drosophila virilis Mitosis [PDF]
In neuroblast cells homologous chromosomes tend to pair during prophase of mitosis. Heterochromatic elements of homologous chromosomes are widely separated in very early prophase, at which time the euchromatin is poorly stained.
