Nuclear quark distribution functions, obtained in the framework of the multiquark cluster model, show that the EMC effect can be explained by taking into account the scattering on colourless multiquark configurations in nuclei. The prediction for the behaviour of the nuclear structure function in the kinematical region X>1, which has not been sufficiently studied experimentally, is given. The Drell-Yan cross sections for lepton pair production in proton-platinum at 440 GeVc-1 and pion-tungsten at pion energy 280 GeV interactions were calculated in addition to the prediction of the behaviour of cross-section ratios in different kinematical regions. The predictions show significant nuclear effects in these processes.
