Once the exchange of homologous sections of the chromosomes is complete, the protein network holding the two homologous chromosomes together will dissipate, allowing them to separate once again. At this point, once the cell enters metaphase, the homologous chromosomes will begin lining up in pairs ...
As NAHR, gene conversion can occur between homologous sequences located within the same chromatid, sister chromatids, homologous chromosomes and non-homologous chromosomes (see Fig. 2). However, gene conversion constitutes a unique type of genomic rearrangement since, in all possible scenarios, it e...
the close association of two homologous chromosomes via the Synaptonemal Complex (SC), which was complete at pachytene. From diakinesis to metaphase I, 19 discrete bivalents were identifiable in all cells (Fig.2a). They consisted of pairs of homologous chromosomes bound together by chiasmata, ...
Type II DNA topoisomerases (topo II) flip the spatial positions of two DNA duplexes, called G- and T- segments, by a cleavage-passage-resealing mechanism. In living cells, these DNA segments can be derived from distant sites on the same chromosome. Due t

Failure to properly restore fork function, particularly if it occurs on both sides of the ICL, could lead to partially unreplicated chromosomes and chromosomal breakage upon mitotic entry. Although much remains to be known, it is clear that the Protexin complex and its associated proteins play a...
