Intro:
In a major advance in genetics, scientists at Northwestern University have uncovered what researchers describe as a hidden second layer of human DNA. By mapping how the genome folds and shifts inside living cells, the team has revealed how the physical structure of DNA helps control gene activity.
The research, conducted with the 4D Nucleome Project and published in Nature, offers a new understanding of how genetic instructions operate beyond the DNA sequence itself.
Conclusion & research article link:
By linking DNA folding, chromatin loops, and gene regulation, the study provides a more complete picture of how genetic instructions function inside cells. Scientists report that this new perspective could lead to improved diagnostic tools and more precise therapies based on genomic structure.
The findings mark an important step toward understanding how this hidden second layer of DNA influences human health and disease.
