Red arrows indicate the nuclear spin axes at the positions of the N3 nitrogen atoms on the guanine (G) bases. Due to the helical structure of DNA, there is an angular deviation in the orientation of ...

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...

The promise of genome editing to help understand human diseases and create new therapies is vast, but technological limitations have limited advancement of the field. While existing editing ...

While most known types of DNA damage are fixed by our cells’ in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

A new international study suggests that ancient viral DNA embedded in our genome, which were long dismissed as genetic "junk," may actually play powerful roles in regulating gene expression. Focusing ...

Schematic showing a single DNA duplex bridging two gold electrodes (yellow) patterned on a silicon nitride substrate (green). The setup allows measurement of electrical conductance as metal ions bind ...

Tokyo University of Science researchers have created optimized DNA hydrogels with possible biomedical uses by utilizing reduced Takumi-shaped DNA nanostructures. The study was published in the Journal ...

Hydrogels are polymeric materials with three-dimensional network structures containing large amounts of water. They serve as sustained-release drug delivery systems as they can encapsulate various ...
