This is a set of 4 Scientifically accurate DNA Models. Each model is a different way of viewing the model all for one low price. It comes with: DNA Ladder Model DNA Space Filling Model DNA Stick Model DNA Ball and Stick model Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The main role of DNA molecules is the long-term storage of information. DNA is often compared to a set of blueprints or a recipe, or a code, since it contains the instructions needed to construct other components of cells, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.
