Damaged DNA may stall patrolling molecule to initiate repair

Sites where DNA is damaged may cause a molecule that slides along the DNA strand to scan for damage to slow on its patrol, delaying it long enough to recognize and initiate repair. The finding suggests that the delay itself ...

Blocking a fork in the road to DNA replication

A team of Whitehead Institute scientists has discovered the surprising manner in which an enigmatic protein known as SUUR acts to control gene copy number during DNA replication. It's a finding that could shed new light on ...

YEATS protein potential therapeutic target for cancer

Federal Express and UPS are no match for the human body when it comes to distribution. There exists in cancer biology an impressive packaging and delivery system that influences whether your body will develop cancer or not.

How to remove tangles in your DNA

(Phys.org) —DNA damage is a fact of life. On any given day, an organism's DNA will suffer between 10,000 and 1,000,000 breaks or other damage. These problems are repaired by enzymes in our cells that fix the breaks, remove ...

Ancient protein-making enzyme moonlights as DNA protector

Scientists at The Scripps Research Institute (TSRI) have found that an enzyme best known for its fundamental role in building proteins has a second major function: to protect DNA during times of cellular stress.
