See INSIDE a Chrysalis! - Painting Wings with CRISPR

Butterfly metamorphosis is still a bit of a mystery. What happens inside a chrysalis to turn a caterpillar into a beautifully painted butterfly? Does it really turn to soup? I visited Dr. Arnaud Martin, who uses the CRISPR genetic modification technology to learn about how genes build bodies. Dr. Martin uses CRISPR to disrupt certain genes, and then looks for changes in butterfly wing patterns, creating designs we never see in nature. This tells us which genes control which part of the "wing painting" process. In the process of visiting Dr. Martin’s lab, I had my mind blown about what REALLY happens during butterfly metamorphosis. You will too.
