WebIn C. elegans, the synapsis checkpoint selectively removes nuclei with unsynapsed 5 chromosomes by inducing apoptosis. This checkpoint depends on Pairing Centers (PCs), cis- 6 acting sites that promote pairing and synapsis. We have hypothesized that the stability of 7 homolog pairing at PCs is WebDec 16, 2005 · We have investigated the role of pairing centers (PCs), cis-acting sites required for accurate segregation of homologous chromosomes during meiosis in C. …
