Cancer genomes are the result of diverse mutation processes that have often accumulated over decades. Scientists have analyzed the molecular evolution of tumors after exposure to mutagenic chemicals.

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 ...

Scientists at Stanford University have discovered that DRT3, a unique defense system found in bacteria, creates DNA to ...

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 ...

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 ...

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 ...

Johnson and Alistar competed as finalists in CU Boulder’s 2025 Lab Venture Challenge where their technology generated much interest from industry leaders. Access to DNA is crucial in many branches of ...

Researchers at the University of Geneva have built a molecular system that can tell the difference between a cancer cell and a healthy one, then selectively destroy the tumor cell while leaving normal ...
