Meiotic cells respond to DNA damage triggering diverse repair mechanisms in a cell cycle-dependent manner. Sequential activation of these mechanisms contribute to accurately maintain genome integrity. However, when spermatocytes are exposed to exogenous DNA damaging agents, like gamma radiation, repair homeostasis may be stressed and chromosomes sometimes engage in aberrant connections with non-homologous chromosomes. Super-resolution fluorescence image (STED) of two meiotic bivalents labelled with an antibody against the SYCP3 protein of the synaptonemal complex. Parallel lines represent the trajectory of homologous chromosomes within each bivalent. A protein filament bridges from one bivalent to the other, connecting two non-homologous chromosomes.
