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 ...

A University of Iowa-led study has revealed the unexpected structure adopted by the DNA repair protein RAD52 as it binds and protects replicating DNA in dividing cells. This new structural and ...

Subscribe to our newsletter for the latest sci-tech news updates. Now, Northwestern University chemists have developed a new approach that replaces a tedious, unpredictable process with intentional ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

DNA can be damaged by normal cellular processes as well as external factors such as UV radiation and chemicals. Such damage can lead to breaks in the DNA strand. If DNA damage is not properly repaired ...

Determining protein structures requires crystals, but getting proteins to crystallize has long depended on a slow, unpredictable process of trial and error ...

DNA repair proteins act like the body's editors, constantly finding and reversing damage to our genetic code. Researchers have long struggled to understand how cancer cells hijack one of these ...

Whether you’re interested in why a living system works as it does or the reasons it goes awry, proteins are a critical part of the molecular picture. The proteins circulating in a person’s plasma can ...

A newly discovered protein from Earth’s toughest animal is inspiring breakthrough therapies for cancer and cardiovascular disease. In 2016, researchers uncovered one of the tardigrade’s secrets: a ...
