The green fluorescent protein (GFP), a valuable tool for visualizing proteins in living cells, is naturally derived from which organism?
Explanation
GFP is a widely used reporter protein. Its origin is a key piece of information provided in the section 'Fusion Proteins and Immunofluorescence Can Localize Proteins in Cells'. The text clearly identifies the jellyfish Aequorea victoria as the source.
