We apply the full one-loop corrections to the masses, gauge couplings, and Yukawa couplings in the minimal supersymmetric standard model. We focus on predictions for the strong coupling and the bottom-quark pole mass in the context of SU(5) supersymmetric grand unification. We discuss our results in both the small and large tanβ regimes. We demonstrate that the finite (non-logarithmic) corrections to the weak mixing angle are essential in determining αs and mb when some superpartner masses are light. Minimal SU(5) predicts acceptable αs and mb only at small tanβ with SUSY masses of \cal O(TeV). The missing doublet model accommodates gauge and Yukawa coupling unification for small or large tanβ, and for any SUSY mass scale. In the large tanβ case, the bottom mass is acceptable only if the Higgsino mass parameter μ is positive.
