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.
