Abstract
A shear flow induces the assembly of DNAs with the sticky spots. In order to strictly interpret the
mechanism of shear-induced DNA assembly, Brownian dynamics simulations with the bead-spring
model were carried out for these molecules at various ranges of the Weissenberg numbers sWed. We
calculate a formation time and analyze the radial distribution function of end beads and the
probability distribution of fractional extension at the formation time to understand the mechanism of
shear-induced assembly. At low Weissenberg number the formation time, which is defined as an
elapsed time until a multimer forms for the first time, decreases rapidly, reaching a plateau at We
=1000. A shear flow changes the radial distribution of end beads, which is almost the same
regardless of the Weissenberg number. A shear flow deforms and stretches the molecules and
generates different distributions between end beads with a stickly spot. The fractional extension
progresses rapidly in shear flow
