DNA-pairing and annealing processes in homologous recombination and homology-directed repair. [PDF]
Cold Spring Harbor Perspectives in Biology, 2015 The formation of heteroduplex DNA is a central step in the exchange of DNA sequences via homologous recombination, and in the accurate repair of broken chromosomes via homology-directed repair pathways. In cells, heteroduplex DNA largely arises through the activities of recombination proteins that promote DNA-pairing and annealing reactions. Classes of

Regulation of DNA pairing in homologous recombination. [PDF]
Cold Spring Harbor Perspectives in Biology, 2014 Homologous recombination (HR) is a major mechanism for eliminating DNA double-strand breaks from chromosomes. In this process, the break termini are resected nucleolytically to form 3' ssDNA (single-strand DNA) overhangs. A recombinase (i.e., a protein that catalyzes homologous DNA pairing and strand exchange) assembles onto the ssDNA and promotes ...

C-DNA may facilitate homologous DNA pairing.
Trends in Genetics, 2023 Recombination-independent homologous pairing represents a prominent yet largely enigmatic feature of chromosome biology. As suggested by studies in the fungus Neurospora crassa, this process may be based on the direct pairing of homologous DNA molecules.

The embedded homology of hypergraph pairs
Journal of Knot Theory and Its Ramifications, 2022 In this paper, we generalize the embedded homology groups of hypergraphs initially given in [S. Bressan, J. Li, S. Ren and J. Wu, The embedded homology of hypergraphs and applications, Asian J. Math. 23(3) (2019) 479–500] and study the relative embedded homology groups of hypergraph pairs. We prove some long exact sequences as well as a Mayer–Vietoris

Frontiers in Plant Science, 2021 Genomic architecture facilitates chromosome recognition, pairing, and recombination. Telomeres and subtelomeres play an important role at the beginning of meiosis in specific chromosome recognition and pairing, which are critical processes that allow ...

Differing requirements for RAD51 and DMC1 in meiotic pairing of centromeres and chromosome arms in Arabidopsis thaliana. [PDF]
PLoS Genetics, 2012 During meiosis homologous chromosomes pair, recombine, and synapse, thus ensuring accurate chromosome segregation and the halving of ploidy necessary for gametogenesis.

Meiotic chromosome pairing is promoted by telomere-led chromosome movements independent of bouquet formation. [PDF]
PLoS Genetics, 2012 Chromosome pairing in meiotic prophase is a prerequisite for the high fidelity of chromosome segregation that haploidizes the genome prior to gamete formation. In the budding yeast Saccharomyces cerevisiae, as in most multicellular eukaryotes, homologous

Homolog Pairing at the Push of a Button [PDF]
Developmental Cell, 2019 Homologous chromosomes pair in somatic cells in Drosophila, but how this occurs is poorly understood. In this issue of Developmental Cell, Viets et al. (2019) show that proteins and chromatin structure mediate pairing and argue against a DNA sequence-based mechanism.

Determinants of Chromosome Architecture: Insulator Pairing in cis and in trans. [PDF]
PLoS Genetics, 2016 The chromosomes of multicellular animals are organized into a series of topologically independent looped domains. This domain organization is critical for the proper utilization and propagation of the genetic information encoded by the chromosome.
