An Example of a Gene Product Encoded by a Regulatory

Question

An example of a gene product encoded by a regulatory gene is:
A)beta-galactosidase enzyme.
B)allolactose.
C)repressor protein.
D)an operator.
E)a terminator.

Accepted Answer

A regulatory gene codes for a repressor protein, which can bind to an operator and prevent transcription of a downstream gene. Therefore, of the options given, the best choice for a gene product encoded by a regulatory gene is a repressor protein (choice C).
