The genes encoding luciferase,green fluorescent protein (GFP),and β-galactosidase are typically used in cloning as
A) transcription regulators.
B) global control genes.
C) promoter sequences.
D) reporter genes.

Question

Quizplus · Accepted Answer

These genes are commonly used as reporter genes which allow researchers to monitor gene expression and protein localization. Luciferase and GFP emit light and fluorescence, respectively, which can be easily detected and measured. β-galactosidase can convert colorless substrates into colored products, allowing for easy visualization of its expression.
