KorB switching from DNA-sliding clamp to repressor mediates long-range gene silencing in a multi-drug resistance plasmid, Nature Microbiology (2025). DOI: 10.1038/s41564-024-01915-3 ...

How cells respond to mitochondrial DNA (mtDNA) damage is not fully understood. This study uncovers a mechanism of mtDNA clearance following damage, driven by the exonuclease activity of the mtDNA ...

Now, researchers used cryoelectron microscopy (cryo-EM) to elucidate the structure of the Nipah virus polymerase complex (the large protein and phosphoprotein). Not only that, but they also ...

Comparison of that ancient DNA with modern human DNA showed that the two species had interbred and that people today still carry the genetic fingerprint of that intermixing. Since then ...

This KorB-KorA regulatory system shuts down bacterial gene expression, KorB acting as a DNA sliding clamp and KorA as a lock which holds KorB in place. Together this complex shuts off gene expression ...

Three students from Centreville High School in Clifton discovered a potentially harmful substance – DNA residues, or tiny fragments of genetic material – in Pfizer’s messenger RNA COVID-19 ...

Of course, though, testing a child's parentage based on physical features is far too subjective — that's typically where DNA tests come in. Such tests can offer a far more scientific way of ...

Learning about your genetics and ancestry is easier than ever. All you need to do is choose from the many DNA ancestry tests available online, receive your kit and send back the required DNA samples.

“For many of the traits DNA kits are testing for – sensitivity to fats and coffee, Omega-3 requirements and the like – there are scores of genes involved”, argues Dr Ordovás. “The genes ...
