DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave.
Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...
Labs around the world are trying to turn cells into autobiographers, tracking their own development from embryos to adults. By Carl Zimmer Shortly after conception, a fertilized egg divides, becoming ...

Those 'DNA knots' weren't knots at all, and the truth is stranger
For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a ...
The original version of this story appeared in Quanta Magazine. For a molecule of RNA, the world is a dangerous place. Unlike DNA, which can persist for millions of years in its remarkably stable, ...
When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...
Scientists have recently been learning more about the importance of small bits of circular genetic material known as extrachromosomal DNA (ecDNA). These little circles of DNA can hitch a ride with ...
The herpesvirus can manipulate our DNA with far more precision than previously thought. The virus condenses and changes the shape of our genetic material to hijack the host genes needed for ...
