Q.
Why glucose and galactose cannot act as an inducer
for lac operon?
Molecular Basis of Inheritance
Solution:
An inducer binds with the repressor protein and
prevents the repressor protein from binding to the
operator.
Glucose and galactose cannot act as an inducer because
these do not have the binding sites for attaching the
repressor protein.
