Green Fluorescent Protein (GFP) is found in the Jellyfish species Aequoria Victoria. GFP is a special protein because it has fluorescent properties due to its ability to emit light at a certain wavelength. The single gene which codes for GFP is inserted into the DNA of a cell and it is produced during protein synthesis. GFP is used as a probe to monitor the movement and location of a protein of interest[1]. GFP is also useful in the minor impact it has upon an organisms physiology when used, meaning it can locate a protein of interest without having an effect on the organism itself[2].
