A compound known as X-Gal is widely used in molecular genetic research. When wild-type (normal) E. coli is grown on medium containing X-Gal, the bacterial colonies turn blue. In contrast, when lacZ mutants are grown on medium containing X-Gal, the bacterial colonies remain their normal white color. What is X-Gal likely to be? a compound that cannot be transported into lacz mutants a compound that can only be transported into lacA mutants a compound chemically similar to lactose a compound chemically similar to glucose a compound chemically similar to galactose
