                                    The Molymod® system is a unique system of high quality molecular models. The set consists of a variety of atom parts and links designed to make a large number of possible structures relevant to a specific chemistry subject or use, e.g. Biochemistry, Organic or Inorganic. All sets are fully compatible. Atom parts are made of solid clouded plastic spheres. They are available with holes from 1 to 6 in the usual angular orientations.

                                    The advanced miniDNA® system comprises colour-coded, abstract-shaped parts designed to represent the nitrogenous bases, pentagonal sugar and pyramidal phosphate components needed to make a double-helix model of DNA.  The three hydrogen bonds that connect Cytosine to Guanine and the two that connect Thymine to Adenine are represented by the appropriate number of pegs.Two DNA kits are available to make either a 12-layer (1 turn) or 22-layer (2 turns) DNA model.  The models can be displayed on their stands, or unzipped into a ladder form to demonstrate the process of Replication.A similar approach can be taken with the two RNA kits to model the process of Protein Synthesis.
