DNA / RNA Amino Acid expansion set

My previous Amino Acid Expansion set needed a way to hold together. Following along with the DNA / RNA set that can be strung together, I decided to put holes through these amino acid pieces so you can use string to hold them together.

This will help in class as you build large proteins, and can help at science fairs where you can attach these as display pieces.
