What are two examples of organisms where Green Fluorescent Protein (GFP) is expressed in biology?

• A. Rats and frogs
• B. Mice and mosquitos
• C. Bacteria and yeast
• D. Fish and lizards

Answer: (B)

Green Fluorescent Protein (GFP) is widely used in molecular and cellular biology as a marker for gene expression and protein localization. The correct examples of organisms where GFP is expressed include mice and mosquitoes.

In mice, GFP is often used in transgenic models to study gene function and regulation in various physiological and developmental contexts. The ability to visualize GFP expression in live tissues or cells provides valuable insights into biological processes, allowing researchers to track the behavior of specific cells and proteins over time.

Mosquitoes have also been genetically modified to express GFP for various research purposes, including studying the biology of the mosquito, investigating pathogen interactions, and developing strategies for vector control. The expression of GFP in these organisms allows researchers to observe and analyze cellular behaviors and developmental stages within living systems.

This highlights the versatility and utility of GFP across different organisms, particularly in laboratory settings for biological research.
