How were glo fish created?

GloFish are genetically modified fish that have been engineered to express fluorescent proteins. This was achieved by inserting a gene from a jellyfish into the DNA of a zebrafish. The jellyfish gene encodes a protein that absorbs blue light and emits green fluorescent light. When this gene is expressed in zebrafish, the fish will glow under blue light.

The glo fish was first created in 1999 by a team of scientists at the National University of Singapore. The team was led by Dr. Zhiyuan Gong, who was inspired by the bioluminescent jellyfish that he saw while scuba diving in the Maldives. Dr. Gong and his team isolated the jellyfish gene that encodes the fluorescent protein and then used a microinjection technique to insert the gene into the DNA of zebrafish embryos.

The first glo fish were green, but subsequent generations of fish have been engineered to express other colors, including red, orange, yellow, and blue. GloFish are now sold in pet stores around the world.

The creation of glo fish has raised some ethical concerns. Some people believe that it is wrong to genetically modify animals for aesthetic purposes. Others argue that glo fish are harmless and that they provide a unique and educational experience for pet owners.

Ultimately, the decision of whether or not to purchase a glo fish is a personal one. However, it is important to be aware of the ethical concerns that have been raised before making a decision.
