Homologous recombination is that which we are taught about in introductory biology class. It is the crossing-over process observed during meiosis, though it occurs in bacteria as well. The process involves pairing up of similar DNA sequences, with then one sequence replacing the other, or indeed for meiotic crossing over, with the generation of now two recombinant strands, one for each chromosome homolog, rather than just one. In either case, key is that it is DNA that is highly similar in terms of DNA sequence that is being either replaced or swapped. This allows for a replacement of alleles following horizontal gene transfer, or allele swapping... 2, record 1, English, - homologous%20recombination

Genomic DNA is maintained with high fidelity to guarantee the integrity of genetic information. Damaged DNA must be properly repaired by sophisticated DNA repair systems to sustain cell viability and genomic stability. Homologous recombination is the major pathway for repairing DNA double strand breaks and for re-initiating stalled replication forks in E. coli and eukaryotes. In E. coli, there are several important proteins involved in homologous recombination : RecA protein is essential for pairing homologous DNA, and for promoting the strand exchange process. 2, record 2, English, - recA%20protein

La protéine recA, expression du gène du même nom, joue un rôle essentiel dans le processus de recombinaison homologue, qui permet la réparation de l’ADN chez Escherichia coli. La protéine recA a pour effet de dissocier les deux brins d’un ADN normal pour permettre l’excision d’une séquence destinée à complèter une brèche d’un ADN dont les deux brins sont lésés irréversiblement. Ainsi au cours de la réplication si un des deux ADN produits est anormal et ne contient plus d’information, l’autre ADN, dissocié par recA, détachera un de ses brins pour le recombiner avec l’autre ADN : de sorte qu’il y aura de chaque côté un brin porteur de l’information et que les enzymes de réparation pourront complèter les deux doubles hélices avec la même information. 1, record 2, French, - prot%C3%A9ine%20recA

In a polyploid derivative of an interspecific hybrid each parental chromosome is represented twice(amphidiploid) or one genome occurs twice and the other only once(sesquidiploid). So there is a choice of pairing between homologous chromosomes(autosyndesis) or homologous chromosomes(allosyndesis). For estimating the amount of allosyndesis in a polyploid derivative of an interspecific hybrid, allosyndetic bivalents should also be taken into consideration in addition to multivalents. 2, record 7, English, - allosyndesis

The new karyotyping methods introduced by Schrock et al use fluorescent dyes that bind to specific regions of chromosomes. By using a series of specific probes each with varying amounts of the dyes, different pairs of chromosomes have unique spectral characteristics. A unique feature of the technology is the use of an interferometer similar to ones used by astronomers for measuring light spectra emitted by stars. Slight variations in color, undetectable by the human eye, are detected by a computer program that then reassigns an easy-to-distinguish color to each pair of chromosomes. The result is a digital image rather than film, in full color. Pairing of the chromosomes is simpler because homologous pairs are the same color, and aberrations and cross-overs are more easily recognizable. In additional, the spectral karyotype has been used to detect translocations not recognizable by traditional banding analysis. 1, record 8, English, - spectral%20karyotyping
