Significats de homologous chromosomes en anglès

Recombination is the exchange of information between two homologous chromosomes during meiosis.

Meiotic recombination is defective and homologous chromosomes separate prematurely during prophase I.

It polymerizes onto DNA and promotes strand exchange between homologous chromosomes.

Faithful segregation of homologous chromosomes at meiosis requires pairing and recombination.

The dynamics by which homologous chromosomes pair is currently unknown.

The first division is preceded by an extended prophase wherein homologous chromosomes undergo recombination.

We also found an increased similarity between homologous chromosomes that have begun to pair.

Meiosis is a specialized cell division during which homologous chromosomes can exchange genetic material through recombination.

During meiosis, the arrangement of homologous chromosomes is tightly regulated by the synaptonemal complex (SC).

The synaptonemal complex (SC) is a tripartite protein scaffold that forms between homologous chromosomes during meiosis.

We find that gene conversions are more likely to occur in regions where the homologous chromosomes are more similar.

Since each complex represents a set of paired homologous chromosomes, it follows that the haploid chromosome number of this protist is nine.

In this case also each pair would be formed by two homologous chromosomes, the one of paternal, the other of maternal origin.

In Drosophila and other Dipterans, homologous chromosomes are in close contact in virtually all nuclei, a phenomenon known as somatic homolog pairing.

The lack of breakpoint heterogeneity may be the result of a U-type exchange involving particular sequences on either homologous chromosomes or sister chromatids.

Faithful chromosome segregation in meiosis is crucial to form viable, healthy offspring and in most species, it requires programmed recombination between homologous chromosomes.
