Query: How molecular knots can pass through each other   We propose a mechanism in which two molecular knots pass through each other
and swap positions along a polymer strand. Associated free energy barriers in
our simulations only amount to a few $k_{B}T$, which may enable the interchange
of knots on a single DNA strand.
