Question

All of the following are used as bioluminescent tools for cell biologists except:

a) Green Fluorescent Protein (GFP)
b) Luciferase
c) Aequorin
d) Polymerase Chain Reaction (PCR)

Answer 1

The correct answer is c) Aequorin. Aequorin is not commonly used as a tool in cell biology research. Options a), b), and d) are commonly used in cell biology.

Step-by-step explanation:

The correct answer is c) Aequorin. Aequorin is a bioluminescent protein derived from a type of jellyfish. It is not commonly used as a tool in cell biology.

On the other hand, options a), b), and d) - Green Fluorescent Protein (GFP), Luciferase, and Polymerase Chain Reaction (PCR) - are all extensively used in cell biology research.
