In all forms of gene therapy, DNA exerts its influence from within the nucleus. Recombinant events for viral delivery of plasmid DNA are permanent and alter the genomes of the affected cells and their ...

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 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 ...

There’s more to dna than just the double helix we know and love: under some conditions this familiar molecule can take on ...

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

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 ...

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 ...

Using DNA, the blueprint of life, U.S. researchers said they have made a three-dimensional structure from particles of gold in a development that could lead to a host of custom-designed materials. The ...
