M5 L1: Gizmo Lab Building DNA Prior Knowledge Questions (Do these BEFORE using the Gizmo.) DNA is an incredible molecule that forms the basis of life on Earth. DNA molecules contain instructions for building every living organism on Earth, from the tiniest bacterium to a massive blue whale. DNA also has the ability to replicate, or make copies of itself. This allows living things to grow and reproduce. 1. Look at the DNA molecule shown at right. What does it look like? This shape is called...
