DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave. Researchers have now mapped this hidden architecture in unprecedented detail, showing ...

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 identified the specific structural loops in G-quadruplex DNA that allow it to act as a chaperone, preventing ...

Estrogen is known as an important hormone, and it can control many functions by regulating the activity of hundreds of genes.

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 ...

For James Watson, DNA was everything — not just his life's work, but the secret of life itself. Over his long and storied career, Watson arguably did more than any other scientist to transform a ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature.

James Watson, who co-won the Nobel Prize for discovering DNA's structure, was a towering and controversial figure in science. When you purchase through links on our site, we may earn an affiliate ...

His decoding of the blueprint for life with Francis H.C. Crick made him one of the most important scientists of the 20th century. He wrote a celebrated memoir and later ignited an uproar with racist ...
