GFP

GFP, or Green Fluorescent Protein, is a protein originally found in jellyfish that glows bright green under specific light. Scientists have harnessed this natural glow as a marker in biological research. By attaching the GFP gene to other genes or cells, they can visualize and track those cells or proteins under a microscope. This allows researchers to study biological processes like gene expression, cell movement, and interactions in living organisms in real-time. GFP has become an essential tool for understanding complex biological systems in medicine, genetics, and cellular biology.
