Six feet of DNA crammed into a cell nucleus narrower than a human hair: ...

Inside human cells, biology has pulled off the ultimate packing job, figuring out how to fit six feet of DNA into a nucleus ...

Scientists have explained how liquid-like droplets made of proteins and DNA form in vitro. Currently, there is a huge interest in understanding the molecular mechanisms behind the creation of such ...

In a world first, researchers have identified a new DNA structure -- called the i-motif -- inside cells. A twisted 'knot' of DNA, the i-motif has never before been directly seen inside living cells.

A breakthrough live-cell sensor makes DNA repair visible as it happens, unlocking new possibilities in biology and medicine.

DNA is the genetic material used by every living organism. But, in a few edge cases, the four bases of DNA—adenine, thymidine, cytosine, and guanine—undergo chemical modifications. And in viruses, ...

Because I find it hard to relate to something as small as the structure of the human genome, I like to imagine it scaled up a millionfold. At this size, each DNA molecule—a chromosome—is as wide as a ...

Nano plumbing: An artistic rendering showing how DNA nanotubes could connect artificial cells. (Courtesy: Schulman Lab, Johns Hopkins University) Synthetic cells, engineered to mimic some of the ...

A group led by researchers at Baylor College of Medicine has identified significant differences at the epigenetic level – the chemical tags in DNA that help regulate gene expression – between two ...
