Why was genetic engineering glow mouse was created?

The Glow-in-the-Dark Mouse, also known as the GFP (green fluorescent protein) mouse, was created primarily for research purposes. By incorporating a gene that produces green fluorescent protein from jellyfish, scientists can visualize and track gene expression and cellular processes in living organisms. This innovation aids in understanding disease mechanisms, testing new drugs, and studying developmental Biology. The glow-in-the-dark feature serves as a tool to observe and monitor biological activities in real-time.
