Molymod DNA Double Helix Model, 22 Segments, miniDNA Kit
Product ID: 684090320
Advantages · Simple differentiation of components by means of six easily distinguishable colours · Representation of hydrogen bonds between thymine and adenine and the three hydrogen bonds between cytosine and guanine · Representation of major and minor grooves on the surface of the double helix · Purine bases (adenine guanine) and pyrimidine bases (cytosine thymine) differ in size Molecule model kit for a right-handed double helix with colour-coded components for representing the bases containing nitrogen as well as pentoses and phosphate groups from which DNA is composed Can be used to demonstrate DNA replication in model as well as complementary base pairing Supplied with assembly instructions and stand Contents 11 Thymine (orange) 11 Adenine (blue) 11 Guanine (green) 11 Cytosine (yellow) 44 Deoxyribose (red) 44 Phosphate (purple) Dimensions approx 44x11x11 cm³ Weight approx 500 g Review: It's not as easy as it looks - It's a pain to put together, and wouldn't stay straight till I gave it a good whacking. Still, once I got it up, it stayed up, showing the major and minor grooves, and the alignment of the riboses. It's a bit of an effort, but if you're into biochem and have some money to burn, it's fine. Review: Très bien - RAS

It's not as easy as it looks
It's a pain to put together, and wouldn't stay straight till I gave it a good whacking. Still, once I got it up, it stayed up, showing the major and minor grooves, and the alignment of the riboses. It's a bit of an effort, but if you're into biochem and have some money to burn, it's fine.

Per studenti del liceo
Regalato a mia figlia, l’ha trovato utile e semplice da utilizzare (ovviamente se si hanno basi minime di genetica)

Ottimo articolo didattico
È un ottimo articolo sia per me che ho studiato questa materia, sia per insegnare. I vari pezzi che compongono il DNA sono ben definiti, si riconoscono facilmente sia le basi azotate che puriniche e pirimidiniche. A fine montaggio ero veramente contento dell'acquisto.
