Scientists have discovered a new structure inside human cells: a never-before-seen twisted "knot" of DNA. Dubbed the "i-motif," this four-stranded knot looks totally different from the iconic double ...

This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

Researchers have used DNA origami, the art of folding DNA into desired structures, to show how an important cell receptor can be activated in a previously unknown way. The result opens new avenues for ...

Researchers have achieved the most detailed view yet of how DNA folds and functions inside living cells, revealing the physical structures that ...

Newly developed artificial intelligence (AI) programs accurately predicted the role of DNA’s regulatory elements and three-dimensional (3D) structure based solely on its raw sequence, according to two ...

Every face carries a story, shaped long before birth by a quiet choreography of genes switching on and off at just the right moment. A new study suggests that part of that story reaches far back into ...

Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in ...

DNA can mimic protein functions by folding into elaborate, three-dimensional structures, according to a study from researchers at Weill Cornell Medicine and the National Heart, Lung, and Blood ...

By the time James Watson died earlier this month at the age of 97, he was one of the world’s most famous — and infamous — scientists. In 1953, he and three fellow researchers co-discovered the ...
