In this Nucleic Acid Biobits Kit, the Phospho-ribose and Phospho-deoxyribose units forming the backbone of RNA and DNA are represented by flexible PVC tubing which is reinforced with wire and punched to receive the purines and pyrimidines. These bases are moulded so that they fit easily into the backbone and can simply be joined by the hydrogen bonds.

The general kit contains enough components for the construction of transfer RNA and of DNA and RNA double helices.

The colour coding clearly shows the A-T, G-C and A-U base pairing, thus the principles of replication and transcription to RNA are easily demonstrated.

• Supplied with full instruction booklet.

Also available as a smaller pre-assembled model (B8A02574).
