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 known as Transcription.
