Test: DNA Structure And Function! Quiz - Quiz

DNA transports genetic information through its chemical structure and molecular behavior. DNA is a molecule that encompasses the instructions on organism needs to build, live, and reproduce. These rules are found inside every cell and are passed down from parents to their children. There are three stages of DNA. These include chemical structure, double helix, and the function of DNA. This quiz may pique your curiosity, and we promise you will enjoy it.
