DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave.

A Northwestern Medicine study has revealed a previously unknown connection between two fundamental cellular processes, ...

MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...

At school, it's often presented as a tidy double helix but scientists are revealing the varied and intricate shapes of DNA molecules. DNA is a molecule found in just about every living cell. Because ...

DNA isn't just a long string of genetic code, but an intricate 3D structure folded inside each cell. That means the tools used to study DNA need to be just as sophisticated-able to read not only the ...

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have mapped out the molecular structure of a key part of our chromosomes called telomeres, which play a pivotal part in ...

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 ...

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to some ...
