We discuss the ordinary, nonsupersymmetric SO(10) as a theory of fermion masses and mixings. We construct two minimal versions of the Yukawa sector based on 126{sub H} and either 10{sub H} or 120{sub H}. The latter case is of particular interest since it connects the absolute neutrino mass scale with the size of the atmospheric mixing angle {theta}{sub A}. It also relates the smallness of V{sub cb} with the largeness of {theta}{sub A}. These results are based on the analytic study of the second and third generations. Furthermore, we discuss the structure of the light Higgs and the role of the Peccei-Quinn symmetry for dark matter and the predictivity of the theory.
