Help your fellow builder by leaving your feedback based on these three criteria:
- Originality: How original is this - never seen before?
- Building Techniques: How much skill do you think the creator of this MOC has, in terms of building technique?
- Details: Express how much you like the details of the build.
Your feedback is only shown to the creator as well as yourself. It is not available for other users to see. The creator won't see your user name.
Swiss researcher Johann Friedrich Miescher made the initial discovery of DNA in 1869, but it wasn’t until 1953 that the double helix model we think of today was first proposed by James Watson and Francis Crick. This discovery was a huge milestone in the field of science, shaping the future of molecular biology.
This model demonstrates the regular structure of DNA as defined by Watson and Crick. Everything is constant: the orientation, the width between nucleotides, and the ten nucleotides per helical turn.
Adenine (blue) always appears opposite thymine (red). They are held together by two hydrogen bonds displayed in yellow.
Guanine (orange) always appears opposite cytosine (green). They are held together by three yellow hydrogen bonds.
I've updated this model to add more color and upgraded the stand to make it look like a glass case. With approximately 256 pieces and a size of 37.5 x 12.1 x 8.3 cm (14.5 x 4.8 x 3.3 in), this design is practical for everyday STEM and Lego building fun.
