The Blueprint of Life

Imagine a library containing every instruction needed to build and run your body — from your eye colour to how tall you'll grow. This "library" exists in almost every cell in your body. It's called your genome, and it's written in a chemical language called DNA. Just 4 "letters" (A, T, C, G) combine in different orders to create all the diversity of life on Earth!
