Learn how researchers at St. Jude, led by Hai Dao, PhD, discovered the mechanisms behind PARP1-mediated DNA repair.

The study, published in Proceedings of the National Academy of Sciences of the United States of America, deepens ...

A team of laboratory, data-management, and biometric examination experts within the FBI Laboratory recently used a combination of administrative and financial prowess, strategic cross-training, and ...

It’s tricky to make an exact copy of yourself. Or at least it is for cells undergoing mitosis, where cells replicate everything inside of them, including their neatly packaged DNA, then split in half.

Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by DNA damage. Among the most dangerous lesions are DNA interstrand crosslinks ...

An apparent large-scale operation Friday night tied to the disappearance of 84-year-old Nancy Guthrie marks a "significant escalation" in the Arizona case, with investigators now racing to canvas ...

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 ...

Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...
