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

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

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 ...

The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break—when both ...

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 closeup look at colibactin’s structure reveals chemical motifs that guide its mutation-wreaking “warheads” to specific stretches of DNA.

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, ...

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 ...

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 ...

Tiny repeated stretches of DNA in your genome may quietly shape how your body works, how your brain develops and how you ...
