Abstract: We present high statistics results for the structure of the nucleon from amixed-action calculation using 2+1 flavors of asqtad sea and domain wallvalence fermions. We perform extrapolations of our data based on differentchiral effective field theory schemes and compare our results with availableinformation from phenomenology. We discuss vector and axial form factors of thenucleon, moments of generalized parton distributions, including moments offorward parton distributions, and implications for the decomposition of thenucleon spin.
