Following a method outlined previously, the Appelquist-Carazzone theorem is applied directly to the problem of breaking the SU(5) grand unified theory down to the standard SU(3) x SU(2) x U(1) theory. This is carried out within the context of the mass-independent renormalization scheme, which necessitates the calculation of the anomalous-mass-dimension matrix of the intermediate vector bosons. A relation between the strong coupling constant and the Weinberg angle is determined. The mass of the leptoquark vector boson is estimated.
