The conserved ATPase PCH-2 controls the number and distribution of crossovers by antagonizing their formation in Caenorhabditis elegans

open access: yeseLife
Meiotic crossover recombination is essential for both accurate chromosome segregation and the generation of new haplotypes for natural selection to act upon. This requirement is known as crossover assurance and is one example of crossover control.

Immunofluorescent analysis of the structure of synaptonemal complex damage induced by xenobiotics in mice spermatocytes

open access: yesФактори експериментальної еволюції організмів, 2013
Aims. The aim of this study was a comparative analysis of the effects of 1,1-dimethyl hydrazine (1,1-DMH) – a component of rocket fuel, and anti-cancer drug cyclophosphan (CP) to the structure of the synaptonemal complex (SC) of male mice and selection ...
