homologous recombinationLinker of nucleoskeleton and cytoskeleton complexmeiosissynapsisMeiosis is a specialized cell division that occurs in sexually reproducing organisms, generating haploid gametes containing half the chromosome number through two rounds of cell division. Homologous chromosomes pair and prepare...

PAR-TERRA binds throughout the genome, including to the PAR and Xic. During X-chromosome pairing, PAR-TERRA anchors the Xic to the PAR, creating a 'tetrad' of pairwise homologous interactions (Xic–Xic, PAR–PAR, and Xic–PAR). Xic pairing occurs within the tetrad. Depleting PAR-TERRA ...
Commonly accepted precepts are challenged: (1) that homologous chromosome pairing is normally mediated by nuclear envelope attachment sites; (2) that crossover site establishment awaits synaptic completion; and (3) that it is the function of the synaptonemal complex to hold homologues in register so...
12). Consistent with the BUSCO analysis, 14 of these 17 enzymes were encoded by homologous genes with a copy number of 4 or a multiple of 4, while the remaining three enzymes were encoded by homologous genes that were tandemly duplicated. Three HMGR genes and three HDR genes were tandemly ...
The PAIR2 gene is required for homologous chromosome synapsis at meiosis I in rice (Oryza sativa L.) and encodes a HORMA-domain protein that is homologous to Saccharomyces cerevisiae HOP1 and Arabidopsis ASY1. Immunocytological and electron microscopic analyses indicate that PAIR2 proteins associate...
Normally, each human cell contains two copies of each chromosome, one inherited from the mother, maternal chromosomes, and one from the father, paternal chromosomes. The maternal and paternal chromosomes of a pair are called homologous chromosomes. The only nonhomologous chromosome pairs are the sex...
The human sex chromosomes share a pair of homologous genes which independently encode a cell-surface antigen defined by the monoclonal antibody 12E7 (refs 1, 2; see refs 3, 4 for review). The X-located homologue, MIC2X , escapes X-inactivation 5 and the equivalent Y-located locus, MIC2Y...
The AZFb is prone to NAHR [non-allelic homologous recombination] with AZFc, resulting in two frequent deletions of, 6.23 and 7.7 Mb. The 6.23 Mb, complete or classic AZFb deletion [P5/proximal P1] corresponds to the interval encompassed between amplicons yel3 and yel1 (Fig. 2) and occurs...
First, a single metaphase lymphocyte cell that contained homologous chromosomes (one pair of homologous chromosomes is shown in blue and red) was selected by a microinjection system. Second, the cell was carefully transferred to a drop of cell lysis buffer, and the chromosomes were released from...
