"When Watson and Crick described the DNA double helix, they were looking at a tiny part of a real genome, only about one turn of the double helix," University of Leeds researcher Sarah Harris says ...

Certain DNA sequences can form structures other than the canonical double helix. These alternative DNA conformations—referred to as non-B DNA—have been implicated as regulators of cellular ...

Researchers have imaged in unprecedented detail the three-dimensional structure of supercoiled DNA, revealing that its shape is much more dynamic than the well-known double helix.

One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double helix.

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 ...

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 ...

The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they ...

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. Credit for the ...

If you were asked to picture a molecule of DNA, chances are you would visualize a long, straight, right-handed double helix—the type you were taught in science class.

Two historians argue that while DNA double helix discoverers James Watson and Francis Crick relied on research from Rosalind Franklin, Franklin was more a collaborator than victim.

New research predicts the location of DNA sequences that can form structures besides the canonical double helix — non-B DNA — in the recently released telomere-to-telomere genomes of the great ...
