Story summary

Researchers at the University of Seville report that phosphorylation of the BRC-1/BRD-1 protein complex in Caenorhabditis elegans acts as a switch to prevent meiosis-related DNA damage.
When this mechanism fails, it causes severe DNA breaks and embryo viability is lost.
The study also identifies two enzymes, Bloom and Mus81, that exacerbate DNA damage.
The findings underscore DNA repair's role in fertility and may inform future research on human reproductive disorders.
