Combining magnetic tweezers and single-molecule fluorescence microscopy to probe transcription-coupled DNA supercoiling
Previous studies have shown that translocation of an actively transcribing RNA polymerase leads to local increases or decreases in DNA torsion (twin-supercoiled domain), which cannot be resolved in vivo due to interactions of the template DNA, nascent RNA and polymerase with the crowded cellular env...
