1 Ιαν 2023 · In this review, we discuss the changes in chromatin conformation taking place between somatic and meiotic cells, with a special focus on the establishment of a proteinaceous structure, called the chromosome axis, at the beginning of meiosis.
27 Μαΐ 2020 · Early pachynema was defined as complete autosomal synapsis, whereas the X and Y chromosomes could display various configuration: i) unsynapsed, with thickened PAR axes; ii) engaged in PAR...
During the lengthy meiotic prophase, all autosomal chromosomes synapse, by forming a special protein structure called the synaptonemal complex, which connects the chromosomal axes. In contrast, the X and Y chromosome synapse only in the short homologous pseudoautosomal regions, and form the so-called XY body. 1 In this specialized chromatin ...
10 Σεπ 2019 · Chromosome axes play a central role in meiotic chromosome dynamics: The axis assembles in early meiotic prophase (leptotene/zygotene) and is required to initiate meiotic recombination and homolog recognition ( 2, 3 ).
5 Ιαν 2023 · Introduction. Homologous recombination during meiosis underlies biological diversity and ensures proper chromosome segregation during the first division to create haploid gametes.
23 Μαρ 2006 · Chromosoma - Meiotic recombination proceeds in biochemical complexes that are physically associated with underlying chromosome structural axes. In this study, we discuss the organizational basis...
9 Αυγ 2021 · The synaptonemal complex (SC) is a supramolecular protein assembly that mediates synapsis between homologous chromosomes during meiosis. SC elongation along the chromosome length (up to 24 μm)...
