Web1 day ago · The synaptonemal complex (SC)–a tripartite proteinaceous structure that forms between homologous chromosomes during meiosis–is thought to regulate CO formation . Both the chromosome axes and the SC are likely under increased physical stress near inversion breakpoints due to formation of inversion loops ( Fig 1 ). WebThe entire structure is termed the synaptonemal complex, which is fully formed by pachytene. In diplotene, the transverse filaments detach and the cores separate for most of their length but remain together at the chiasmata, the points of genetic recombination.
WebJun 20, 2014 · The synaptonemal complex (SC) is an evolutionarily-conserved protein assembly that holds together homologous chromosomes during prophase of the first meiotic division. Whilst essential for meiosis and fertility, the molecular structure of the SC has proved resistant to elucidation. The SC protein SYCP3 has a crucial but poorly … WebSynaptonemal Complex. 117 Sycp3 mutant females show increased aneuploidy, in which the abnormal karyotype is ...
