M6L2 Gizmo Lab: Cell Division Cells reproduce by splitting in half, a process called cell division. What do cells need to do between divisions to make sure that they don’t just get smaller and smaller? Based on these two observations, would you say that a cell spends most of its life cycle in interphase or in mitosis/cytokinesis?

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...
