The discovery of Hoogsteen base pairs, an alternative pairing mode to the canonical Watson–Crick structure, has significantly broadened our understanding of DNA dynamics. This conformation, in which ...
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 ...
In the search for the chemical origins of life, researchers have found a possible alternative path for the emergence of the characteristic DNA pattern: According to the experiments, the characteristic ...
Molecular models are a tried-and-tested tool for teaching chemistry to students of all ages. By enabling users to visualize the three-dimensional structure of a molecule and how its atoms are arranged ...
In Wikipedia, there are 21 scientists listed who made significant contributions to determining the structure of DNA. In recent decades the focus has been on the contributions of only 3 of those ...
COLUMBUS, Ohio -- Shape-shifters aren't just the stuff of fiction, they're real--and they're inside our DNA. In the Feb. 1 issue of the journal Nature, researchers describe how two normally mismatched ...
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, ...
Scientists have sequenced a South American lungfish genome, revealing 91 billion DNA base pairs. This is 30 times more DNA than humans, setting a new record. The discovery ranks as the largest animal ...
