As a first step toward developing a reaction model that enables acomprehensive description of neutrino-nucleon reactions in the nucleonresonance region, we have applied for the first time a dynamicalcoupled-channels model, which successfully describes \pi N, \gamma N --> \pi N,\eta N, \pi \pi N, K\Lambda, K\Sigma reactions up to W = 2 GeV, to predict theneutrino-induced meson-production reactions with \Delta S = 0 at the forwardangle limit. This has been achieved by relating the divergence of theaxial-current matrix elements at Q^2 = 0 to the \pi N --> X reaction amplitudesthrough the PCAC hypothesis. We present the contributions from each of the \piN, \eta N, \pi \pi N, K\Lambda, K\Sigma channels to the F_2 structure functionat Q^2 --> 0 limit up to W = 2 GeV.
