For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a double helix. That picture is still right, but it is no longer enough.

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 ...

Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such structure, the G-quadruplex (G4), looks like a knot. These knots can play ...

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.

Google's new AI tool can read DNA like a language, and see immediately if a word substitution will change the meaning of that sentence, the company says. — © AFP ...
