DNA is well-known for its double helix shape. But the human genome also contains more than 50,000 unusual knot-like DNA structures called i-motifs, researchers at the Garvan Institute of Medical ...

Scientists have mapped tens of thousands of mysterious "knots" in human DNA, and they may play a key role in controlling gene activity. Knowing the exact locations of these knots — known as "i ...
