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.

New ultra-detailed imaging exposes the hidden structure and behavior of chromatin condensates — and hints at how their ...

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 ...

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

Scientists continue to inch closer and closer to medical breakthroughs by tinkering with DNA. At the end of 2016, the CRISPR gene-editing tool was used for the first time on human cancer patients, and ...

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 ...

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

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 ...
