This is part of the series of 30 exercises developed during the E3D+VET program. The aim of this Erasmus+ program is the immersion in 3D printing of VET centres (website: https://www.e3dplusvet.eu/).

This exercise is composed by 24 interchangeable “puzzle” pieces and a base, where one can put the DNA Base puzzle pieces.

• The base ground is a rectangular piece in which 6 puzzle pieces can be allocated;
• Each DNA base piece is suggested to be painted with a different colour for better distinction;

There are 4 bases (Adenin, Cytosine, Guanine, and Thymine). Each base has a matching base (A and T match; C and G match) Each base piece features the letter of its Name (A= Adenin, C= Cytosine, G= Guanine, and T = Thymine)

For a more difficult level the Bases can all have the same end so it will not be so obvious which base matches with which one.
