Scientists 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 ...

Deep in coastal mangroves and even inside our own mouths, biologists are finding that DNA does not always sit in a simple ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...

Breaks in our genetic code termed “DNA double-strand breaks” create cellular stress and cell death if not rapidly repaired. Environmental mutagens including UV light can cause DNA breaks, and these ...

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 ...

In certain toy racecar tracks, sneaky players can flip a switch, trapping their opponents' vehicles in a loop of track. Cells employ a less subtle approach: they change the track's layout. In a study ...

Scientists from the Kavli Institute of Delft University of Technology and the IMP Vienna Biocenter discovered a new property of the molecular motors that shape our chromosomes. While six years ago ...
