What the World’s Smallest Tweezers Tell Us About DNA

The video explores the use of optical tweezers, a tool that uses light to manipulate small particles, in studying DNA. It explains the challenges of isolating DNA strands due to their complex packaging in cells. Optical tweezers, discovered in 1986, allow scientists to separate DNA strands by applying radiation pressure. This has led to insights into DNA structure, histone binding, and DNA's mechanical properties. Understanding these details is crucial for studying chromatin's role in diseases and developing better treatments.
