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 ...

Inside every human cell, six feet of DNA folds into a nucleus that is only a few micrometers wide, yet still manages to ...

Inside human cells, biology has pulled off the ultimate packing job, figuring out how to fit six feet of DNA into a nucleus ...

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 ...

Studying how single DNA molecules behave helps us to better understand genetic disorders and design better drugs. Until now however, examining DNA molecules one-by-one was a slow process.

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 ...

Proteins are essential biological molecules that perform a vast array of functions crucial for life, from catalyzing biochemical reactions and transporting molecules to providing structural support ...

One of the most important milestones in modern science, does April 25 also mark the date of an intellectual heist? As has been well-documented, a third person contributed to the discovery — the ...

James D Watson, the brilliant but controversial American biologist whose 1953 co-discovery of the structure of DNA, the molecule of heredity, ushered in the age of genetics and provided the foundation ...

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 ...
