Series of assays and recombinant constructs are presented hereinafter that establish the connections between the regulatory region of a first gene, and the product of a second gene. The regulatory region of the first gene is inserted into a recombinant construct, and linked downstream to it is the cDNA of the second gene and then the regulatory region of the second gene is inserted into a recombinant construct, and linked downstream to it is the cDNA of the first gene, and in every recombinant construct either the cDNA of the gene or the regulatory region is that of a cell cycle gene. The recombinant constructs are then transferred into the cells and the degree of activation of the regulatory elements are sorted out.
