Most biochemistry labs that study DNA isolate it within a water-based solution that allows scientists to manipulate DNA without interacting with other molecules. They also tend to use heat to separate ...

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 ...

In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

New research from a team of genome scientists and DNA damage response experts breaks new ground in understanding the function of a protein currently limited in clinical trials for cancer treatments.

For the first time, researchers have filmed in real time the disassembly of DNA at the atomic scale. This strand separation is the first step in DNA replication. This breakthrough, published in Nature ...
