Fluorescent transgenic mouse being held in the hand of a researcher. This mouse glows green under blue light as it contains a protein (green fluorescent protein, GFP) from a glowing jellyfish (Aequorea victoria). The egg from which this mouse developed was infected with a virus carrying the jellyfish gene, causing the gene to be incorporated into the mouse's DNA. A gene is a segment of DNA (deoxyribonucleic acid) which has a specific function, in this case the production of GFP in the mouse's cells. This genetic engineering technique could be used to mark cancer cells in human patients follow their movement around the body. | |
