This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

The results of this collaborative project overturn some conventional wisdom about how the DNA repair process works. DNA is often likened to a blueprint. The particular sequence of As, Cs, Gs, and Ts ...

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 ...

When people think of DNA, they visualize a string-like double helix structure. In reality, the DNA double helix in cells is supercoiled and constrained into loops. This supercoiling and looping are ...

Scientists from Oxford's Radcliffe Department of Medicine have achieved the most detailed view yet of how DNA folds and ...

Scientists have constructed ''DNA droplets'' comprising designed DNA nanostructures. The droplets exhibit dynamic functions such as fusion, fission, Janus-shape formation, and protein capture. Their ...

Tiny tweaks in DNA folding can have big effects. A study from Umeå University shows that even the most subtle changes in DNA’s shape have an important influence on gene activity and energy production.

Neurons are the anatomical and functional unit of the nervous system, regulating both vital functions and higher functions. Among the very few cells in the body that do not regenerate, these cells ...

Inside every cell, a finely tuned metabolic network determines when to build, recycle, or stop producing essential molecules.
