From which animal is the gene for Green Fluorescent Protein (GFP) derived?

• A. Sea anemone
• B. Starfish
• C. Jellyfish
• D. Cuttlefish

Answer: (C)

The gene for Green Fluorescent Protein (GFP) is derived from the jellyfish Aequorea victoria. This protein exhibits fluorescence and has become a vital tool in molecular biology and genetics for visualizing proteins and cellular processes. The discovery of GFP in jellyfish was significant because it enabled researchers to utilize this naturally occurring fluorescence for tagging and imaging cellular structures in live organisms. The properties of GFP, such as its ability to be expressed in a wide range of organisms, enhance its utility in various scientific applications. This innovative use of a naturally occurring protein highlights the connection between biological research and the unique traits found in different marine species.
