High-resolution imaging has revealed the internal layout of chromatin condensates, showing how DNA fibers fold and interact ...

Inside every human cell, six feet of DNA folds into a nucleus that is only a few micrometers wide, yet still manages to ...

DNA might be too small to see with the unaided eye, but it packs our cells in shocking quantities: More than six and a half feet of DNA lies within every cellular nucleus. It squeezes into such a ...

Before cells can divide, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Until now, scientists had believed that ...

Evo’s success wasn’t limited to proteins. When they tested a different toxin that had an RNA-based inhibitor, the system ...

New work from UC Davis and the University of Utah shows how the 3D structure of DNA inside a germ cell commits it to develop into a sperm cell. The discovery could improve understanding of fertility ...

Researchers at Duke University used CRISPR technologies to discover previously unannotated stretches of DNA in the 'dark genome' that are responsible ...

Tiny tweaks in DNA folding can have big effects. A study from Umeå University shows that even the most subtle changes in DNA's shape have an important influence on gene activity and energy production.
