Learn more about a new experimental procedure that uses cancer cells’ DNA repair system against itself to make drug-resistant ...

Cancer cells survive by repairing damage to their DNA—even damage that would normally be fatal. One of their most important ...

Researchers at Baylor College of Medicine have identified a previously unknown defense mechanism in blood vessel cells that helps slow atherosclerosis by repairing DNA damage. The study shows that ...

Loss of an enzyme necessary for a process called lipoylation disrupts the way cancer cells copy their DNA, increasing their ...

From proofreading polymerases to complex backup repair systems, DNA repair is a high-yield MCAT topic that bridges molecular biology and human health. Understanding the mechanisms that safeguard ...

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

Gene expression is controlled, in part, by the interactions between genes and regulatory elements located along the genome.

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by researchers at Goethe University Frankfurt, part of the Rhine-Main University ...

A team of Israeli researchers has found that one of the reasons that sleep could be so important to animals — including humans — is that it takes neurons 'offline' so DNA damage accumulated during ...

Cars patched up after a wreck may look fixed—but never run quite as before. The same may hold true for chromatin, according to a study published in Science on November 6. In response to double-strand ...
