This model is prepared to assemble biological macromolecule such as DNA or proteins, It is designed with 1A=1cm so that the assembled molecule should not occupy so much space. Moreover, it is light and is steady matched combination of parts and is manufactured so as not to collapse the conformation of the molecule. Strong polyacetate resin is used for the material to wear out, and coloring the black, red, blue, yellow, and white which distinguishes easily each other.
