DNA is the building block of all life. This book helps children aged 8 plus understand the structure of the DNA chemical, how it works inside the body, how life began on Earth and how all living things are connected by their DNA. With Nigel Baines' hilarious cartoons, the book explores topics such as why some of us really don't like Brussel sprouts - and why some of us love them!; what came first - the chicken or the egg?; and how DNA can solve crimes and make our lives better.
