The intrinsic ability of double-stranded DNA to carry out D-loop and R-loop formation
Double-stranded (ds)DNA, not dsRNA, has an ability to form a homologous complex with single-stranded (ss)DNA or ssRNA of homologous sequence. D-loops and homologous triplexes are homologous complexes formed with ssDNA by RecA/Rad51-family homologous ...

Modeling cell biological features of meiotic chromosome pairing to study interlock resolution.
During meiosis, homologous chromosomes become associated side by side in a process known as homologous chromosome pairing. Pairing requires long range chromosome motion through a nucleus that is full of other chromosomes.

Competition of Parental Genomes in Plant Hybrids
Interspecific hybridization represents one of the main mechanisms of plant speciation. Merging of two genomes from different subspecies, species, or even genera is frequently accompanied by whole-genome duplication (WGD).

Synaptonemal complex components persist at centromeres and are required for homologous centromere pairing in mouse spermatocytes. [PDF]
Recent studies in simple model organisms have shown that centromere pairing is important for ensuring high-fidelity meiotic chromosome segregation. However, this process and the mechanisms regulating it in higher eukaryotes are unknown.

Meiotic Nuclear Oscillations Are Necessary to Avoid Excessive Chromosome Associations
Pairing of homologous chromosomes is a crucial step in meiosis, which in fission yeast depends on nuclear oscillations. However, how nuclear oscillations help pairing is unknown.

The pairing of homologous chromosomes is a fundamental feature of the meiotic cell. In addition, a number of species exhibit homolog pairing in nonmeiotic, somatic cells as well, with evidence for its impact on both gene regulation and double-strand ...

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

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.

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.
