It was by understanding DNA’s double-helix form that science was able to begin ... James Watson and Francis Crick discovered the the twisted-ladder structure of DNA in 1953, a finding that gave.

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 ...

In 1953, James Watson and Francis Crick discovered the now-famous "double helix" DNA structure. But scientists have previously observed short lengths of DNA in different shapes.

The DNA double helix. Structure and Components. DNA consists of 2 polynucleotide chains or strands, wound around each other such that they resemble a twisted ladder. This structure is referred to ...

Watson and Crick ultimately used Franklin's images, along with their own evidence for the double-stranded nature of DNA, to argue that DNA actually takes the form of a double helix, a ladder-like ...

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 ...

New York — 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.

The most famous image to emerge from 20th-century biology is the deoxyribonucleic acid (DNA) double helix, illustrating the structure of the gene, life’s genetic material.

However, compaction isn’t enough. Cells also need to regulate the chromosome structure to enable its function. For example, when genetic information needs to be accessed, the DNA is locally read off.
