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

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 double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

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 ...

James Dewey Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped launch a revolution in biology and medicine, died Thursday at age 97. He died in hospice care after a brief ...
