This is a remix of my DNA / RNA manipulative set, which can be found here http://www.thingiverse.com/thing:1259352

Lesson Plans and lab work is now available on my teacher pay teacher site, https://www.teacherspayteachers.com/Product/3D-Printable-DNA-RNA-Manipulative-Lab-1-3452084
When I presented the original version to my biology class, students asked if there was a way to display or string the pieces together to stabilize them. We thought more about it, and I realized that these could be be strung together like a necklaces. They could also be displayed for science fairs and presentations.
So I remixed the set to include 3 mm holes through all the pieces so you can thread floss through them.
You can print these pieces in different colors like I did in the DNA / RNA set, I just prototype them in lime green.
If you want to help students see how A, T and C, G pair together, print the tiles in two different contrasting colors. This way they can see how each pair together.
If you want to display these on the whiteboard, use flexible magnetic tape to stick these on the whiteboard.
REVISIONS FOR V2 Files
Dis D V2 12.stl: The shape was changed to prevent students from fitting the prior D piece together with the A in the wrong location.
Dis 35 V2.stl: The 3 prime and 5 prime pieces have been reshaped.
Dis A V2 6.stl: The A piece is now the larger one to better match the chemical size. The A lettering has been moved to make room for the holes for the string.
Dis T V2 6.stl & Dis U V2.stl: Both have been corrected to be smaller then A.
Dis G V2 6.stl: The odd offset has been corrected, and letter moved.
