DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave.

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 ...

In 1963, Popular Science reported on the Nobel Prize-winning discovery, and the woman who was left out of the accolades. By Bill Gourgey Published May 31, 2022 7:00 AM EDT Get the Popular Science ...

An international team working at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has captured the first high-resolution 3-D images from individual double-helix DNA ...

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to some ...

DNA is the genetic material used by every living organism. But, in a few edge cases, the four bases of DNA—adenine, thymidine, cytosine, and guanine—undergo chemical modifications. And in viruses, ...

Arizona State University researchers Hao Yan and Yan Liu imagine and assemble intricate structures on a scale almost unfathomably small. Their medium is the double-helical DNA molecule, a versatile ...

Scientists have found that twisting structures in DNA long mistaken for knots are actually something else entirely. Inside cells, DNA gets twisted, copied, and pulled apart. The twists can influence ...
