Model to show the double-helix structure of DNA.
We have two models of DNA.
The shorter model is a 10 layer DNA model consisting of five two-layer model kits assembled for a 3-D version of a double helix.
The taller model depicts a 16 base pair section built to a scale of 1nm to 10cm. The phosphate and deoxyribose are accurately portrayed and can be removed and separated for further examination. Individual base pairs can also be removed.
DNA is a moleule that carries the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses. DNA and ribonucleic acit (RNA) are nucleic acids; alongside proteins, lipids, and complex carbohydrates (polysaccharides), they are one of the four major types of macromolecules that are essential for all known forms of life. Most DNA molecules consist of two bipolymer strands coiled around each other to form a double helix.
