Bovine presents a complex genome due to high number of repetitive sequences involved in macro and micro-rearrangements that are essential in the bovids evolution. However, it has a morphologically simple karyotype, with acrocentric autosomes (2n=60,XX and 60,XY). The Robertsonian translocation rob(1;29), which produces embryo mortality, has been widely described in different breeds of Bos taurus but the complexity of its mechanism and its consequences in chromatin changes, are still not clear. Clastogenic agents are used as an approach to study this rearrangement in chromatin structure. Particularly, the aphidicolin (APC) inhibits the eukaryotic DNA polymerase alpha during replication. This fact permit to identify regions rich in dCTP due to a competition...
