The deuteron deep inelastic unpolarized structure function 
is described
using the Wilson operator product expansion method. In the leading twist approximation
the convolution model is restored and an explicit formula for the nucleon distribution
function in the deuteron is presented, accounting for binding effects in a covariant
way. The long distance behavior,
related to the deuteron bound state properties, is evaluated using the
Bethe-Salpeter equation with one nucleon on-mass-shell. The calculation of
the ratio 
is compared with other convolution models showing important
deviations in the region of large x. In part, this deviation can be attributed to
deuteron model dependencies.
