Evidence for a Solenoid Phase of Supercoiled DNA
Andrew Dittmore, Keir C. Neuman
In mechanical manipulation experiments, a single DNA molecule overwound at constant force undergoes a discontinuous drop in extension as it buckles and forms a superhelical loop (a…

Supercoiling DNA locates mismatches
Andrew Dittmore, Sumitabha Brahmachari, Yasuhara Takagi +2
We present a method of detecting sequence defects by supercoiling DNA with magnetic tweezers. The method is sensitive to a single mismatched base pair in a DNA sequence of several…
