Key concepts Biology Life DNA Double helix Introduction Ever wondered how DNA, the genetic blueprint of a life-form, can encode and pass on the information on how to grow and maintain that life ...

The discovery of DNA's double helix structure 70 years ago opened up a world of new science — and also sparked disputes over who contributed what and who deserves credit. Much of the controversy ...

Science Move Over, Double Helix: A New Form of DNA Has Just Been Discovered This is the first time it's ever been seen in a living cell.

The double helix, though, is not the only form in which DNA exists. For the first time ever, scientists have identified the existence of a new DNA structure that looks more like a twisted, four ...

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 ...

Watson and Crick showed that the basic features of DNA were straightforward and led immediately to a highly plausible model for how one DNA molecule could be duplicated to form two identical ...

A new paper based on long-lost documents confirms that DNA discoverer Rosalind Franklin should be credited for discovering the double helix.

Nobel laureate Francis Crick dies at age 88. He and fellow laureate James Watson discovered the double-helix structure of DNA in 1953.
