Untangling DNA with a droplet of water, a pipet and a polymer

27 febrero 2015

Researchers have long sought an efficient way to untangle DNA to study its structure — neatly unraveled and straightened out — under a microscope. Now, researchers have devised a simple and effective solution: they inject genetic material into a droplet of water and use a pipet tip to drag it over a glass plate covered with a sticky polymer.
