Question

Because it is easy to measure the levels of ___________, the lacZ gene which encodes this enzyme can be used as a(n) ___________ gene to detect the amount of transcription that occurs in response to any specific regulatory element.

a) β-galactosidase; Reporter
b) Lactose; Inducing
c) mRNA; Monitoring
d) Repressor; Regulatory

Answer 1

The lacZ gene, which encodes β-galactosidase, can be used as a reporter gene to detect the amount of transcription influenced by specific regulatory elements.

Step-by-step explanation:

The correct answer is a) β-galactosidase; Reporter. The lacZ gene encodes β-galactosidase, an enzyme that can be easily measured. The lacZ gene is often used as a reporter gene to detect the amount of transcription that occurs in response to specific regulatory elements. By measuring the levels of β-galactosidase, researchers can determine the level of transcription influenced by regulatory elements.
