It is assumed that nucleon consists of three quarks with no admixture of gluons or strange quarks. Gluons as are seen in deep inelastic scattering, appear only as a result of bremsstrahlung by valence quarks. The model gives unique predictions for observable quantaties and imitates the scaling behavior at Q2 ≳ 2 GeV2 provided the coupling constant of strong interactions is relatively small at such values of Q2 ( g2(2 GeV2) 4π ≈ 1 4). The predictions of the model agree with the data within (10 - 20) % accuracy and links consideration of deep inelastic scattering with the most naive quark model. The effect of charmed particles production is estimated within the model developed. It is shown that the standard four-quark model of weak interactions is inconsistent with observed anomalies in ν, ν-interactions.
