The Creeper always covers his face, but scientists recently extracted DNA from samples collected at crime scenes in order to create a facial composite for a wanted poster. Such work is far from ...

and special proteins attach to DNA to mechanically unwind the double helix and then pry it apart. "The interior of the cell is super crowded with molecules, and most biochemistry experiments are ...

When most of us think of DNA, we think of that iconic double helix shape. But when you zoom out, DNA gets a lot more complicated. "When Watson and Crick described the DNA double helix, they were ...

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 ...

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 ...

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 ...

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. Researchers have ...

A new paper based on long-lost documents confirms that DNA discoverer Rosalind Franklin should be credited for discovering the double helix. When you purchase through links on our site ...

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. It's well established that ...

in which she successfully used X-ray crystallography to create images of DNA, became the basis for James Watson and Francis Crick’s groundbreaking 1953 discovery of the double helix structure.

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 ...
