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 ...

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

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.

Researchers explore a basic building block used in the fabrication of many DNA nanoforms. Known as a Holliday junction, this nexus of two segments of double stranded DNA has been used to form ...

Fluorogenic DNA aptamers produce light only in the correct structural state, enabling programmable molecular logic, ...

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, ...

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 ...

It's DNA, but not as we know it. In a world first, Australian researchers have identified a new DNA structure - called the i-motif - inside cells. A twisted 'knot' of DNA, the i-motif has never before ...
