Did you know there is a secret, invisible code hidden right inside your body? It is called DNA, and it works like a tiny set of instructions that tells your cells exactly what to do every single day! It looks like a twisted ladder or twirling noodles, and it is the amazing blueprint that makes you a human instead of a poodle. Have you ever wondered why we cannot breathe underwater? Or why some people grow very tall while others stay short? Why do you share traits with your parents and grandparents? Written in incredibly fun, flowing rhymes, this bright picture book answers all these questions by explaining cells and genetics in a brilliantly simple way. It beautifully shows that while DNA determines how you look on the outside, the choices you make about who you want to be are entirely up to you!
