  Deep inelastic scattering of leptons off nuclear targets is analized within
the convolution model taking into account nucleon-nucleon correlations. We show
that in the nuclear medium nucleons are distributed according to a function
that exhibits a sizeable Q**2-dependence and reduces to the ordinary light-cone
distribution in the Bjorken limit. At Q**2 < 50 (GeV/c)**2 and x > 1 this
Q**2-dependence turns out to be stronger than the one associated with the
nucleon structure function, predicted by pertubative quantum chromodynamics.
