DNA is known as the blueprint for life! Found in every cell of every living thing, DNA strands are packed inside a cell's nucleus carrying instructions and genetic information. Climb the double helix ladder and crack the DNA code in this fact-filled life science book to explore genetics and why parts of you may appear identical to your great, great, great grandparent. Fifth-grade readers will learn about DNA structure and replication, proteins and genes, chromosomes, inherited traits and alleles, cloning, and more through this high-interest informational text filled with vibrant photographs. Aligned to the Next Generation Science Standards, a hands-on "Think Like a Scientist" lab activity and a "Your Turn" page at the end of the book support STEM Education and provide young scientists with an opportunity to apply what they've learned in the text. Helpful diagrams, a timeline of genetic discoveries, and text features, such as a glossary and index, are also included to reinforce content-area literacy and improve close reading.
