Genes are instructions that make cells work--like a code--and DNA is what genes are made of. All living things have genes and DNA, so they are an undeniably crucial part of life, evolution, and of a student's learning endeavors. The book's colorful illustrations, achievable text, and informative diagrams guide readers to understanding the inner workings of genes and DNA, as well as providing an enjoyable experience that will have them equally informed and entertained. Genes and DNA may be small, but readers' knowledge of them certainly won't be after reading this book!.
