We report the current status of RBCK calculations on nucleon structure with both quenched and unquenched lattice &CD. The combination of domain wall fermions and DBW2 gauge action works well for quantities like isovector vector and axial charges, moments of structure functions (ST),, dl, and (l)ap,

A genuinely non-perturbative evaluation of higher-twist contributions to the structure functions of the nucleon, with all mixing effects and renormalon ambiguities taken care of, is presented. Higher-twist corrections turn out to be significant at moderate values of q2.

The flavor singlet axial and tensor charges of the nucleon are calculated in lattice QCD. We find AE = Au + Ad+ As = +0.638(54) --0.347(46) --0.109(30) = +0.18(10) for the axial charge and 5E = 5u + 5d + 5s = +0.839(60) -0.231(55) -0.046(34) = +0.562(88) for the tensor charge. The result for the axi
