3B Scientific W19801 DNA RNA Model, 50cm Height

The 3B Scientific W19801 DNA-RNA stationary model includes interlocking parts and a wooden stand. This model demonstrates the structure of DNA and RNA molecules. Interlocking pieces connect to form the double helix shape and show how molecules split at the center of the base pairs. A variety of tubes and spheres represent guanine (red tubes), cytosine (green tubes), thymine (blue tubes), adenine (gray tubes), uracil (white tubes), sugar, hydrogen, and phosphate. White two-prong atom parts represent hydrogen bonds between the base pairs. Black trigonal atom parts represent sugar. Red two-prong atom parts represent phosphate groups. Yellow tubes link phosphate groups to sugar rings. The model includes a wooden base and support rod. The completed model measures 50cm high. DNA and RNA models are commonly used in classrooms and educational settings to teach biology and genetics. Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology. 3B Scientific manufactures anatomical models, simulators, charts, and other training materials for use in scientific, medical, and patient education. The company, founded in 1948 and headquartered in Hamburg, Germany, meets International Organization of Standardization (ISO) standard 9001: 2008. What's in the Box?
