Nanowires are vital components for future nanoelectronics, sensors, and nanomedicine. To achieve the required complexity, it is necessary to control the position and growth of the metal chains on an ...

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 ...

Focusing on the schematic illustration in a, two DNA polymerase molecules are active at the fork at any one time. One moves continuously to produce the new daughter DNA molecule on the leading strand, ...

This video shows replication of individual pieces of double stranded DNA. This is the first time DNA replication -- arguably, the fundamental process of life on Earth -- has been observed directly.

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 ...

When we learn about human genetics in high school biology class, one of the most basic things we learn about is the DNA double helix, the twisting ladder-shaped structure that holds our genetic code.

Biology textbooks may be due for a rewrite. For the first time, scientists have detected a DNA structure inside living human cells that looks more like a four-stranded knot than the elegant double ...

The human genome is usually formed as a double helix, but DNA can assume other configurations such as the four-stranded structure. Four-stranded DNA structures are known as G-quadruplexes (G4) and ...

Researchers from Tokyo Metropolitan University have been studying DNA repair by homologous recombination, where the RecA protein repairs breaks in double-stranded DNA by incorporating a dangling ...

In the early 1990s, Jacqueline Barton, the John G. Kirkwood and Arthur A. Noyes Professor of Chemistry at Caltech, discovered an unexpected property of DNA--that it can act like an electrical wire to ...

(AP/WKRC) - It is one of the most popular but completely untrue stories and visuals of the week. It is not legit, even though shared widely on social media. The Associated Press checked it out. Here ...
