Twist and Stretch of Helices Explained via the Kirchhoff-Love Rod Model of Elastic Filaments

John Maddocks

In various single-molecule experiments, a chiral polymer, such as DNA, is simultaneously pulled and twisted. We address an elementary but fundamental question raised by various authors: does the molecule overwind or unwind under tension? We show that withi ...
