Using an atomic force microscope tip as a pen and different single-stranded DNA as inks, scientists at Northwestern University have demonstrated a technique that could lead to the ultimate ...

Big-picture patterns of DNA packaging, gene activation and mutations could hold the information needed to develop a blood-based biopsy for small cell lung cancer patients, according to new work ...

Mutations are changes in the molecular 'letters' that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...

Researchers use DNA nanotechnology to build layered lattice structures that produce new interference patterns with unique physical properties and nanoscale control. (Nanowerk News) Researchers are ...
