Story summary
- A Nature study by Neil Hunter and team at UC Davis shows meiosis regulates DNA double-strand breaks via double Holliday junctions and ZMM proteins to sustain chromosome synapsis.
- Disruptions can cause improper crossovers, risking infertility and genetic disorders from incorrect chromosome segregation.
- Using techniques, the study highlights cohesin's role in protecting junctions and notes environmental factors may influence crossover rates.
