Homologies in human and Macasa fuscata chromosomes revealed by in situ suppression hybridization with human chromosome specific DNA libraries [PDF]

open access: yes, 1992
We established chromosomal homologies between all chromosomes of the human karyotype and that of an old world monkey (Macaca fuscata) by chromosomal in situ suppression (CISS) hybridization with human chromosome specific DNA libraries.

Mouse HFM1/Mer3 is required for crossover formation and complete synapsis of homologous chromosomes during meiosis. [PDF]

open access: yesPLoS Genetics, 2013
Faithful chromosome segregation during meiosis requires that homologous chromosomes associate and recombine. Chiasmata, the cytological manifestation of recombination, provide the physical link that holds the homologs together as a pair, facilitating ...

Rad62 protein functionally and physically associates with the Smc5/Smc6 protein complex and is required for chromosome integrity and recombination repair in fission yeast [PDF]

open access: yes, 2004
Smc5 and Smc6 proteins form a heterodimeric SMC (structural maintenance of chromosome) protein complex like SMC1-SMC3 cohesin and SMC2-SMC4 condensin, and they associate with non-SMC proteins Nse1 and Nse2 stably and Rad60 transiently.

Genetic Requirements for Intra-Chromosomal Deletions [PDF]

open access: yes, 2020
Chromosomal deletions are one of the most dangerous types of DNA damage and often arise as a result of inappropriately repaired DNA double strand breaks (DSB).

Positive regulation of meiotic DNA double-strand break formation by activation of the DNA damage checkpoint kinase Mec1(ATR) [PDF]

open access: yes, 2013
During meiosis, formation and repair of programmed DNA double-strand breaks (DSBs) create genetic exchange between homologous chromosomes-a process that is critical for reductional meiotic chromosome segregation and the production of genetically diverse ...

Agent-based modeling of nuclear chromosome ensembles identifies determinants of homolog pairing during meiosis.

open access: yesPLoS Computational Biology
During meiosis, pairing of homologous chromosomes (homologs) ensures the formation of haploid gametes from diploid precursor cells, a prerequisite for sexual reproduction.

Extensive DNA end processing by exo1 and sgs1 inhibits break-induced replication.

open access: yesPLoS Genetics, 2010
Homology-dependent repair of DNA double-strand breaks (DSBs) by gene conversion involves short tracts of DNA synthesis and limited loss of heterozygosity (LOH).

Mutations in pathways depending on BRCA1 and BRCA2 may increase cancer risks from an environmental carcinogen [PDF]

open access: yes, 2011
Recently, the President’s Cancer Panel [2008-2009] protested that preventive action is not taken when uncertainty exists about potential harm from a chemical, because the US regulatory approach demands that a hazard be incontrovertibly ...

Rad54: the Swiss Army knife of homologous recombination? [PDF]

open access: yes, 2006
Homologous recombination (HR) is a ubiquitous cellular pathway that mediates transfer of genetic information between homologous or near homologous (homeologous) DNA sequences. During meiosis it ensures proper chromosome segregation in the first division.

Optimal Haplotype Assembly from High-Throughput Mate-Pair Reads

open access: yes, 2015
Humans have $23$ pairs of homologous chromosomes. The homologous pairs are almost identical pairs of chromosomes. For the most part, differences in homologous chromosome occur at certain documented positions called single nucleotide polymorphisms (SNPs).
