Query: Effect of genome sequence on the force-induced unzipping of a DNA
  molecule   We considered a dsDNA polymer in which distribution of bases are random at
the base pair level but ordered at a length of 18 base pairs and calculated its
force elongation behaviour in the constant extension ensemble. The unzipping
force $F(y)$ vs. extension $y$ is found to have a series of maxima and minima.
By changing base pairs at selected places in the molecule we calculated the
change in $F(y)$ curve and found that the change in the value of force is of
the order of few pN and the range of the effect depending on the temperature,
can spread over several base pairs. We have also discussed briefly how to
calculate in the constant force ensemble a pause or a jump in the
extension-time curve from the knowledge of $F(y)$.
