Scientists from Oxford's Radcliffe Department of Medicine have achieved the most detailed view yet of how DNA folds and functions inside living cells, revealing the physical structures that control ...

Scientists have for the first time been able to build a organism containing a new, synthetic pair of DNA units, marking a breakthrough in the field of synthetic biology that has major implications for ...

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, ...

Quantum mechanics, which rules the world of the teensy-tiny, may help explain why genetic mutations spontaneously crop up in DNA as it makes copies of itself, a recent study suggests. If you're ...
