The following data were obtained. A '+' indicates the presence of the enzyme or chromosome in the cell line. A '-' indicates the absence of the enzyme or chromosome in the cell line. On the basis of these results, which chromosome has the gene that codes for the enzyme? chromosome 8 chromosome 1 chromosome 17 chromosome 4 chromosome 2
