A new twist: The molecular machines that loop chromosomes also twist DNA

Dec 13, 2024

Scientists from the Kavli Institute of Delft University of Technology and the IMP Vienna Biocenter have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they have now discovered that these motors also put significant twists into the loops that they form.
