The figure provided portrays the integration of Lambda phage into a host chromosome at the att site, located between the gal+ and bio+ genes. This prophage may disintegrate from the host carrying with it host genes, such as gal+ and/or bio+ and go on to ransduce another host bacterium. How would one determine if a gal- host bacterium's phenotype was changed from gal- to gal+? To clarify, the minus version cannot utilize galactose as a carbon source for growth because it does not produce galactase, the
