AI Summary

Scientists have engineered a tiny DNA rotor that amplifies the motion of protein‑DNA interactions, enabling microscopes to follow gene transcription at the resolution of a single base pair. The device consists of a corkscrew‑shaped stem that attaches to a protein, an X‑shaped handle, and a fluorescent dye probe that together magnify the underlying molecular movement. Researchers suggest that visualizing these mechanical motions is essential for fully understanding and manipulating molecular function.
