Beyond the ladder-like structure described above, another key characteristic of double-stranded DNA is its unique three-dimensional shape. The first photographic evidence of this shape was ...

DNA is negatively charged ... Thus, the 30-nanometer fiber may be highly irregular and not quite the uniform structure depicted in instructive drawings such as Figure 1 (Bednar et al., ...

Scientists at Purdue University and the University of Minnesota have solved the three-dimensional structure of the central component of a biological "motor" that powers the DNA packaging system in a ...

This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations. The structure so perfectly fit the experimental data that it was almost immediately ...

DNA molecules are large and complex. They carry the genetic code that determines the characteristics of a living organism. The diagram shows the relationship between the cell, its nucleus ...

Earlier that morning, in the nearby Cavendish laboratory, the two scientists had discovered the structure of deoxyribonucleic acid, or DNA. This discovery changed the world of science and medicine ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

Using an approach called DNA origami, scientists at Caltech have developed a technique that could lead to cheaper, reusable ...

For instance, it can be twisted or stretched, impacting its overall structure and dynamics. Researchers at the University of York recently explored how DNA behaves under torsion and tension using ...
