Using evidence from Table 2, explain in complete sentences why the bacterial colonies on the starter plates are blue. B. Isopropyl β-D-1-thiogalactopyranoside (IPTG) is used along with X-gal for blue-white screening. IPTG is a non-metabolizable analog of galactose that induces the expression of lacZ gene. It should be noted that IPTG is not a substrate for β-galactosidase but only an inducer. See more Blue-white screening is a rapid and efficient technique for the identification of recombinant bacteria. It relies on the activity of β-galactosidase, an enzyme occurring … See more The presence of lactose in the surrounding environment triggers the lacZ operon in E. coli.
