In The Cell A Tiny City young readers begin to explore the biology of the cell. Students learn that cells are made of special molecules, like protein and DNA. Proteins are molecules that do all of the work inside cells. DNA is a double strand of atoms linked together that has a code that tells cells what to do. Proteins and DNA work together to make the cell function. (students should be familiar with Chemistry Readers, Proteins and DNA)
