One of the most familiar shapes in science is DNA’s double helix structure. First discovered in 1953, this structure uncovered a wealth of information about our genes and the DNA molecules that encode ...

Guided by the work of Rosalind Franklin, James Watson and Francis Crick discovered the the twisted-ladder structure of DNA in 1953, a finding that gave rise to the modern field of molecular biology.

In 1962, scientists James Watson, Francis Crick and Maurice Wilkins received the Nobel Prize in Medicine for discovering the double helix structure of DNA. However, it has long been believed that the ...

Diagrams: Short section of DNA, 1951 -- Chemical structures of the DNA bases, 1951 -- Covalent bonds of the sugar-phosphate backbone -- Schematic view of a nucleotide -- Mg** ions binding phosphate ...

This was a collaborative project by researchers from the National Physical Laboratory (NPL) and the London Centre for Nanotechnology (LCN). To measure and conceptualize large, irregularly arranged ...

One of the first biological molecules characterized by atomic force microscopy (AFM) was DNA. DNA imaging using AFM is often performed for characterizing the structure of DNA, protein interaction, ...

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 ...

Scientists have discovered a new structure inside human cells: a never-before-seen twisted "knot" of DNA. Dubbed the "i-motif," this four-stranded knot looks totally different from the iconic double ...

Double-helix molecules are frequently encountered in biological and synthetic organic systems, where they typically provide improved strength and better electrical properties relative to materials ...

Discovery comes as an extension of the development of a polymer ion-gel, which promises to outperform conventional flammable liquid battery electrolytes. Researchers in the College of Science and ...

The double-helix structure has practically become synonymous with DNA, but it isn't the only way long strands of genetic information squeeze themselves into a tight space. When a double-strand of DNA ...
