CHAMPAIGN, Ill. – Thanks to a single-molecule imaging technique developed by a University of Illinois professor, researchers have revealed the mechanisms of an important DNA-regulating enzyme.

If DNA can be compared to an architect who gets all the glory for designing the building, RNA can be compared to the engineer who often goes unrecognized, but is needed to turn the blueprints into a ...

Helicases are enzymes that unwind DNA and RNA. They're central to cellular life, implicated in a number of cancers and infections - and, alas, extraordinarily difficult to target with drugs. Now, new ...

Genome-wide studies of fission yeast (Schizosaccharomyces pombe) suggest that the evolutionary conserved enzyme Pfh1 helicase facilitates DNA synthesis by tracking along with the replication apparatus ...

For the first time, scientists have captured the exact moment DNA begins to unravel, shedding light on a fundamental chemical process that enables DNA to serve as the blueprint for life. A recent ...
