double-helical model for the structure of DNA. Watson and Crick's discovery was also made possible by recent advances in model building, or the assembly of possible three-dimensional structures ...

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.

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?

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that make up the human genome. But where and how does the famous double helix fit into ...

The ability of DNA to store and replicate information stems from its unique double-helix structure. One can imagine it as an elongated, twisted ladder, where each rung represents a unit of genetic ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...

When this DNA is collected and purified, the result is a whitish, sticky substance that is somewhat translucent. To actually visualize the double-helical structure of DNA, researchers require ...

(Image: Wikimedia Commons, CC SA 3.0) The most common type of base pairing is the Watson-Crick base pair, named after James Watson and Francis Crick, who first proposed the double helix structure of ...

The two decide to team up to create a three-dimensional model of DNA, which they believe must have some type of helical structure. Meanwhile, X-ray crystallographer Rosalind Franklin is hard at work ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event ...

the helix structure is unwound special molecules break the weak hydrogen bonds between bases, which are holding the two strands together this process occurs at several locations on a DNA molecule ...
