Is a homologous pair the two sister chromatids or the two pairs of sister chromatids? What is the difference between meiosis and mitosis? Does each homologous chromosome of a pair has to be on any particular side of the metaphase plate?
Triticum aestivum (2 n = 6 x = 42) is an allohexaploid species in which the three genomes ( A , B and D ] were derived from closely related 14-chromosome diploid species 1 . Every pair of homologous chromosomes has a genetically corre... ...
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 ...
We investigate the CC as it is the most prominent WM bundle in the brain, responsible for communication between homologous brain regions. WM projections through the CC to distinct cortical regions are topographically organized, and local abnormalities in CC morphometry may reflect abnormalities in ...
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...
(e.g. X and Y) begins when a pair of homologous autosomes acquires a sex-determining factor16. Sex-specific genes are typically linked to this factor and recombination becomes suppressed in the heterozygous sex to facilitate inheritance of these genes en bloc. This suppression of recombination ...
