The Molecular Models 14-2700C 17 Base Pair Model Kit is completely assembled, has a rotating base, and stands 3' high. This molecular model of a double helix with 17 base pairs is used in educational settings to teach about . It represents the molecular structure of eight thymine-adenine and nine cytosine-guanine base pairs. Its rotating base provides stability and visibility during classroom demonstrations. The atom parts and links are made from durable plastic and easy to identify by standard color-coding.. Atom parts measure 17mm to 23mm and represent carbon, oxygen, hydrogen, nitrogen, and phosphorus. It comes with an acorn nut, two washers, 16 painted spacers, a stand, a link removal tool, a short bond push tool, and instructions. 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. Molecular Models Company manufactures molecular models for science education. Founded in 1967, the company is headquartered in Beloit, WI.
