Msh4 and Msh5 Function in SC-Independent Chiasma Formation During the Streamlined Meiosis of Tetrahymena
ZMM proteins have been defined in budding yeast as factors that are collectively involved in the formation of interfering crossovers (COs) and synaptonemal complexes (SCs), and they are a hallmark of the predominant meiotic recombination pathway of most organisms. In addition to this so-called class I CO pathway, a minority of crossovers are formed by a class II pathway, which involves the Mus8...

متن کاملThe Evidence for Localized Chiasma Formation
ECENT studies of the highly differentiated pachytene chromosomes of R the tomato have indicated that this plant can be used in the analysis of chromosome structure in relation to chromosome behavior and gene location (BROWN 1949; BARTON 1950). In general, the twelve paired chromosomes of the tomato pachytene complement are differentiated into densely staining (chromatic) regions proximally on e...

results of 50 patients, 20 were men and 30 women with mean age of 61.1 ± 16.9 years ranged between 22 and 85 years. all samples of pterygia had positive results for adenoviruses dna with polymerase chain reaction, but none of the negative control groups displayed adenoviruses. the pterygium group and the control groups were β-globin positive. direct sequencing of pcr products confirmed adenovir...
متن کاملPredicting gene networks in human oocyte meiosis.
Meiosis is the characteristic feature of sexual reproduction; its molecular regulation has been preserved throughout eukaryotic evolution. The defining stage of meiosis is prophase I (Fig. 1), in which homologous chromosomes pair and remain tethered until the first meiotic division, when they must segregate equally into daughter cells that then enter meiosis II. The importance of this stage is ...
