DNA topoisomerase-IA is an essential enzyme that relaxes supercoiled DNA by introducing transient single-strand breaks through a covalent phosphorylated tyrosine (PTR) intermediate. This cleavage ...

Only a few years ago, Tuesday’s announcement that a glove believed to be connected to the disappearance of Nancy Guthrie in Tucson, Arizona, had no match in a DNA database would have been a dead end.

For the first time, researchers have succeeded in developing an artificial DNA base pair that is based on a different chemical force than natural genetic material. While the common natural DNA ...

Although DNA evidence collected in the Nancy Guthrie investigation has yet to yield matches, law enforcement is still bracing for results that could expose cracks in the southern Arizona case ...

TUCSON, Ariz. — As the Nancy Guthrie case enters week three, investigators and the public are awaiting potentially pivotal DNA results tied to a glove recovered near the scene. But according to ...

Scientists have discovered that DNA behaves in a surprising way when squeezed through tiny nanopores, overturning a long-held assumption in genetics research. What researchers once thought were knots ...

The power of artificial intelligence (AI) and advanced computing has made it possible to design genetic sequences encoding for diverse biological applications, such as proteins that form the building ...

Researchers suggest that they have recovered sequences from ancient works and from letters that may belong to the Renaissance genius. Historical artifacts can accumulate DNA from the environment and ...

Our studies show the levels of type I topoisomerases are increased in human papillomaviruses (HPV)-positive cells, leading to enhanced levels of DNA breaks and activation of DNA repair pathways.
