When bacteriophage lambda infects a sensitive bacterium, one of the first messenger RNA species synthesized is very short, beginning at a site P L and extending just through an adjacent gene N. After the appearance of the gene N protein, messages become much longer, still beginning at PL but extending far beyond gene N. The N gene encodes

A panel of cell lines was created by human—mouse somatic-cell hybridization. Each cell line was examined for the presence of human chromosomes and for the production of three enzymes. The following results were obtained: 

On the basis of these results, give the chromosomal locations of the genes encoding enzyme 1, enzyme 2, and enzyme 3.
