Researchers in McGill's Department of Physics have developed a new device that can trap and study DNA molecules without touching or damaging them. The device, which uses carefully tuned electric ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at ...
