In the DNA leveled reader, fundamental science concepts in chemistry are explained through simply written text and colorful, fun illustrations. Children will learn that DNA stands for deoxyribonucleic acid, which is a polymer made of two long strands wrapped around each other in a double helix shape. A polymer is a long chain of atoms and molecules linked together. DNA is found inside the cells of living things and contains four bases: adenine, thymine, guanine, and cytosine. These bases line up in pairs inside the double helix. The sequences of the bases makes a genetic code that is read by proteins and determines many of the characteristics of a living thing. Each person has a different genetic code, making everyone unique. A pronunciation guide of scientific terms is included. 24 pages filled with engaging, colorful illustrations. Reading Level 2-5, Interest Level 2-5.
