During DNA replication, the classic double helix can temporarily rearrange into an alternative structure known as a DNA three-way junction (3WJ). These configurations form a well-defined central ...

In DNA discovery lore, it was Photograph 51—taken in May 1952—that revealed so much about DNA’s helical structure. Four decades later, ...

Despite her contribution to the discovery of DNA's helical structure, Rosalind Franklin was not named a prize winner: She had died of cancer four years earlier, at the age of 37.

Exactly 66 years ago, on April 25, 1953, Francis Crick and James Watson published their famous article that showed that the shape of DNA is a double helix. They weren’t able to see DNA directly ...

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 ...

Since the discovery of the double helix structure of DNA nearly 70 years ago, scientists have worked to understand how the two strands of DNA are opened to access the genetic information they ...

DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

James Watson and Francis Crick proposed that DNA (deoxyribonucleic acid) was a double-helix structure, not a triple stranded structure as had been previously hypothesized, on April 2, 1953. The ...

Enzo di Fabrizio and his team have developed a new technique to produce a direct image of the DNA helix and its inner structure. This is the first time scientists have ever been able to produce an ...

The structure of DNA is widely accepted to exist as a double helix, but different DNA structures also exist. New research points to a range of triggers that can manipulate its shape.

A piece that aired on NPR this week about the discovery of DNA's structure neglected to mention the significant contribution of Rosalind Franklin to that scientific milestone.
