We have performed a QCD next-to-leading order (NLO) calculation for Deep Inelastic Scattering (DIS) retaining the full parton and hadron mass dependencies. We find that the gluon initiated contributions to DIS processes, such as charm production, are \it comparable in magnitude (\it i.e., 30% to 100%) to the ``leading-order'' (LO) sea-quark processes. The ``slow-rescaling" prescription and the full NLO formalism are compared in a quantitative manner. The use of DIS distributions and the inclusion of the charm mass via slow-rescaling are not sufficient to mimic the correct NLO physics. These results imply that previous analyses of charm production data to extract the strange and charm content of the nucleon, as well as the precise determination of Standard Model parameters based on these analyses (such as the Weinberg angle), need to be reassessed.
