DNA doesn't just coil in the iconic double helix immortalized in every high school biology textbook. It also loops into a menagerie of fantastical shapes, new research finds.
By revealing the hidden shape of DNA, the new insights could provide a more detailed look at the workings of drugs such as chemotherapeutic agents, which interact with DNA.
