Not all DNA looks like the familiar double helix. Sometimes, parts of our genetic code fold into unusual shapes under certain conditions. One such structure known as a G-quadruplex (G4) looks like a ...

What scientists long believed were knots in DNA may actually be persistent twists formed during nanopore analysis, revealing ...

G4 and R-loop signals at the indicated genomic locus. Both G4s and R-loops accumulate in cells where the resolution of G4 knots is defective (red). Not all DNA looks like the familiar twisted ladder.

Knots are everywhere—from tangled headphones to DNA strands packed inside viruses—but how an isolated filament can knot itself without collisions or external agitation has remained a longstanding ...
