A Single DNA Letter Change Rewired Sexual Development in Female Mice
Researchers found that altering one DNA base in female mouse embryos was enough to trigger development of male reproductive organs, highlighting the outsized effects tiny genomic changes can have during development.
Key Takeaways
- Researchers altered one DNA base in female mouse embryos and observed development of male reproductive organs.
- The result highlights how powerful specific regulatory DNA sites can be during embryonic development.
