GloFish
GloFish are produced by adding a natural flourescent gene to the fish DNA. a gene called green fluorescent protein which is originally from jellyfish is added to the fish eggs before they hatch. The protein naturally produces bright green bioluminescence and scientists breed them by adding a natural fluorescence gene to the fish. some controversies surrounding glofish include arguments about the fish being an invasive species, threatening entire ecosystems, causing the original stocks to die off, and being more suceptible to disease. I believe glofish should be allowed to the public unless they are causing harm. I would really enjoy having a GloFish of my own to call my pet.
Glow-in-the-dark cats
In 2007, South Korean scientists altered a cat’s DNA to make it glow in the dark and then took that DNA and cloned other cats from it — creating a set of fluffy, fluorescent felines. Here’s how they did it: The researchers took skin cells from Turkish Angora female cats and used a virus to insert genetic instructions for making red fluorescent protein. Then they put the gene-altered nuclei into the eggs for cloning, and the cloned embryos were implanted back into the donor cats — making the cats the surrogate mothers for their own clones.
What’s the point of creating a pet that doubles as a nightlight? Scientists say the ability to engineer animals with fluorescent proteins will enable them to artificially create animals with human genetic diseases.
