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 ...

DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among the most dangerous forms of DNA damage and immediately trigger the cell's ...

Plectonemes are the analog of the twisted tangles of telephone cords, and can form in DNA that is pulled through a nanoscale channel. They are called plectonemes. They are the analog of the twisted ...

The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break-when both sides of the DNA helix are cut at once. Healthy cells can normally fix ...

Scientists have discovered that DNA behaves in a surprising way when squeezed through tiny nanopores, overturning a long-held assumption in genetics research. What researchers once thought were knots ...
