Abstract
We examine the role of quarks and gluons in the proton spin formation in connection with the famous EMC experimental result. The gluon contribution to the DIS generated by the axial anomaly is shown to have a well-defined physical meaning and its gauge invariance properties are clarified. We also emphasize the role of the U(1)-ghost contribution in understanding of the gauge problem and in estimation of the quark spin contribution. Some recent ideas in explanation of the EMC-result and newly proposed experiments are briefly reviewed. (author). 44 refs.
