By: Answerout


Here is the answer for the question - What is the function of the lacZ gene?. You'll find the correct answer below

What is the function of the lacZ gene? A. This gene encodes the repressor of the lac operon. B. This gene encodes an enzyme, galactoside permease, which transports lactose into the cell. C. This gene encodes an enzyme, b-galactosidase, which cleaves lactose into glucose and galactose. D. This gene encodes an enzyme, b-galactosidase, that cleaves lactose into two glucose molecules.

The Correct Answer is

CThe lacZ gene encodes b-galactosidase, a key enzyme in lactose metabolism. When lactose is present in the cell, the cell expresses lacZ and metabolizes lactose.

Reason Explained

CThe lacZ gene encodes b-galactosidase, a key enzyme in lactose metabolism. When lactose is present in the cell, the cell expresses lacZ and metabolizes lactose. is correct for What is the function of the lacZ gene?
