I will discuss the results of recent phenomenological study of unpolarized nuclear structure functions for a wide range of nuclei. As a basis of our phenomenology we develop a model which addresses a number of different mechanisms of nuclear scattering including corrections due to Fermi motion, binding, off-shell modification of the bound nucleon structure functions, nuclear shadowing, nuclear pion excess. The application of this approach to charged-current neutrino-nuclear scattering is also reviewed.
