Deoxyribonucleic Acid

Deoxyribonucleic acid (or DNA) in LEGO(R) form! Now you can build the basic building blocks of life out of the basic building blocks of LEGO!!! It's Basic structure consists of 40 1x2 technic pins with holes, 80 round 1x1s and 40 technic pins.

As you can see from the photo, I built the two helixes from different colours, which makes them stand out quite nicely, so you’ll need twenty of each colour.

And for the base pairs: I don’t think there’s a universally accepted coding. Remember, though, that they only appear in two forms; Adenine only ever bonds with Thymine (A-T) and Guanine only ever bonds with Cytosine (G-C). Twenty of each colour is a good place to start; you’ll certainly have enough to spell out GATTACA. 

Of course, you’re going to need to make about 220 million base pairs if you want to model your own DNA and that’s a whole lot of Lego… Too much for this model, anyway...
