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 ...

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.

For loops are one of the basic structures in coding. There are however many different types of loops. How can we implement various types of loops that we know in languages like Python in Power ...
